Hama - EWS-3000 Wireless Weather Station

Winner: read review
  • In order for the measured data to be displayed correctly, you need to give the device a little time to settle.
  • Try to place the sensor sheltered from the wind so that the data is displayed as accurately as possible and the displayed temperature is not fluctuating.
  • It is recommended to place the outdoor sensor in the shade.
  • Energy-insulated house walls are particularly suitable for installation.
  • To always have the weather station in view, you should place it at a central point.

In the run-up to the test, we defined practical requirements and the following test criteria:

  • Handling
  • Accuracy of data
  • Range
  • Functional scope

In order to evaluate these criteria, we have defined several tests for the weather stations. In these, the stations are first set up and put into operation. We paid attention to whether the date and time are automatically set via radio.

All other display options and functions are also checked. In order to measure temperature and humidity, the sensors of the devices were placed inside, outside and in a cool box for a hardness test. An independent thermometer is used to check that the displayed temperatures are correct.

The maximum range from the sensor to the main unit is also measured. During the entire test series, the devices are checked for user-friendly and clear menu navigation, an easy-to-read display and handling.

The test devices are tested for minus temperatures

In order to rule out errors and to ensure the stress of everyday use, each test takes place in several rounds.

The test criteria are given percentages depending on their importance. The final score is then objectively calculated from the test criteria using an algorithm.

Product selection

Our product selection is based on an observation of the current market. In addition to popular branded products, we also include insider tips in our selection. Criteria such as price and range of functions are an important factor for us. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest).

The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.

As soon as new relevant products come onto the market, our test field is extended by these. The new products go through the same test as the already tested devices.

A weather station serves the collection of daily current weather data. It consists of different meteorological measuring instruments, which supply data at a fixed time.

The measuring devices include the thermometer to measure the outside temperature, the hygrometer to provide data on humidity, a barometer to measure air pressure, as well as the rain gauge and anemometer (for professional weather stations).

In addition, a distinction is made between analogue and digital weather stations. Analog weather stations are small wooden or plastic boxes that carry out weather measurements at fixed intervals. The weather data must then be read off.

With digital weather stations, data is collected and transmitted by cable or radio in real-time. Weather stations are usually used for government weather measurements and forecasts.

Private individuals use simpler weather stations to determine their own weather, which attempt a simple forecast based on the change in air pressure and other measurement data.

A weather station is made up of various measuring devices that provide meteorological data for further analysis. The following five instruments are used for weather measurement:

1. The thermometer

Thermometers measure temperatures in a specific environment. In modern measurement technology, the temperature is measured by means of electrical voltage. The electrical resistance in the wire of the thermometer is compared with the ambient temperature. The measurement result depends on two factors: On the one hand, the choice of material inside the thermometer is decisive. It has been proven that platinum wires have the best measuring properties. On the other hand, it depends on the diameter of the measuring element. These two components make the ideal case possible. This provides for the measured resistance and temperature to behave linearly in relation to each other. This method is considered to be the most accurate method of measuring temperatures.

The best-known thermometer measures temperatures using the cold wire resistance sensor. Commercially available clinical thermometers, for example, are of this type.

Another type of temperature measurement is carried out with a thermocouple. With thermocouples, the measurement takes place via two different metal wires, which are connected together at the intended measuring point and then subjected to electrical voltage. The temperature at the measuring point of the thermometer can then be read off and compared with the known reference temperature. The different voltage in the two metal pieces allows the exact measuring point temperature to be recorded.

2. The hygrometer

The hygrometer measures the humidity in its environment. The measuring principle of a hygrometer is based on the function of the electrical capacitance. The measuring sensor is also known as the substrate. In most cases, it consists of glass, ceramic or plastic. The substrate is applied as a thin layer between the cathode and anode and, depending on the level of humidity, absorbs water vapor or emits steam. If there is a change in humidity, the sensor immediately regulates and measures the changed electrical capacitance and converts it immediately.

The hair hygrometer is the best known measuring device in Germany. The device determines the air humidity with the help of a hair. Hair expands depending on the humidity. In addition to human or animal hair, synthetic fibres are also frequently used. The fibres have a coefficient of expansion similar to that of human hair and are therefore particularly suitable for determining humidity.

The current air humidity can be easily displayed. For this purpose, the hair of the hygrometer is connected with a lever pointer. In this way, changes in humidity are immediately displayed on a scale.

3. The barometer

A barometer measures the air pressure. The can barometer has often proven itself in the past years in air pressure measurement. The measuring process of the barometer is explained by the function of the can, in which a negative pressure prevails, which changes again and again by the changing air pressure strongly. This causes the can to expand as the pressure drops and to compress as the air pressure rises. The measurable changes of the air pressure are transferred to a pointer and can be read off the scale.

For official measurements, on the other hand, the variant of electrical capacitance measurement is used. A small sensor determines each change in air pressure. The sensor already reacts to the slightest changes, the bending membrane skin, which is covered at its ends with tiny electrodes. As the membrane bends, a gap develops which reduces the distance between the electrodes on the membrane skin. This results in a measurable change, from the value of which meteorologists can calculate the air pressure.

4. The precipitation gauge

Rain gauges determine the amount of rain. Frequently weather stations still use the old-weighted rain seesaw. The seesaw is also called the precipitation tipping bucket. It has different chambers, which are arranged in different heights on top of each other. The bowls fill with rainwater. If the amount of precipitation exceeds a certain weight, the scale tilts the pan downwards and the rainwater empties into the next chamber. This process is repeated. Precipitation can be added by the number of tilting movements and the weight of the water chambers.

The latest devices, on the other hand, directly measure the amount of precipitation in a single large chamber and add the sums. One such precipitation gauge is the Hellmann precipitation gauge. The rain falls through an opening into an extra metal housing with a collecting can. To measure the precipitation, the rainwater contained in the can is transferred into a measuring cup and the value is then read off.

5. The wind gauge

Wind gauges or anemometers determine current wind conditions. There are three known types of wind gauges. A useful anemometer is the cup anemometer. This measurement works via three semicircular shells, which show the measurement of the wind speed at the same distance from each other. In addition, there is a wind vane on the anemometer. It indicates the wind direction by blowing to where the wind comes from. However, the cup star has a disadvantage compared to other devices. Due to its inertia, it continues to rotate after the wind impulse, although the still wind has already set in.

The propeller anemometer is the other variant. It has an integrated wind vane and can determine wind speeds and wind directions simultaneously. Since the wind vane always points in the direction where the wind comes from, the propeller is always positioned against the wind and can thus easily measure the maximum speed of the wind. The speed of the airflow is then calculated from the ratio to the propeller revolutions. However, there are also measurement deviations here due to the nature of the equipment.

Nowadays ultrasonic anemometers are most frequently used to determine the wind. The measuring principle works as follows: Two sound impulses travel back and forth between small sensors. The wind speed is thus calculated from the distance of the sensor and the transit time of the pulses. The wind direction is calculated via the axis position of the two sensors. The special feature of ultrasonic measurement, compared to the two other methods, is the significantly faster reaction time of the device.

All meteorological measuring instruments described are ideally mounted in a weather hut. The hut should then be placed in the immediate vicinity of a weather meadow. The German Weather Service (DWD) has compiled a few tips for setting up a weather station in order to enable unadulterated measurement results that can be compared with other weather stations:

  • Precipitation measurement: 1 meter above ground level.
  • Air temperature: 2 meters above the ground.
  • Humidity measurement: 2 meters above the ground.
  • Wind measurement: 10 meters above the ground.
  • Free location of the weather station - there should be no obstacles such as buildings or trees in the vicinity of 10 metres.

The record of the weather goes back to the year 1881. In the late 19th century, however, there was no state weather service. In monasteries and churches, clergymen have always been interested in the interaction between man and nature, so spiritual institutions were commissioned to carry out regular weather measurements and to document the data obtained. However, the history of weather measurement is much older. It dates back to the Middle Ages. It is well known that well-known researchers such as Galileo Galilei were already conducting research into the weather at that time and built their first measuring instruments.

In Germany, a meteorological society was founded many years before the start of weather recording. Mannheim scientists carried out weather measurements at various locations in Germany from 1780 onwards. They determined the exact times at which the measurements were carried out. They documented the weather data three times a day - at 7 a.m. in the morning, at 2 p.m. after lunch and at 9 p.m. at the end of the day. Many years later, these records served as the basis for the development of weather maps and today's climate zones on Earth. By the way, the three measuring hours are still known today. In meteorological circles, one speaks of the "Mannheimer hours".

The sensors can also measure minus temperatures.

The development of Morse radio technology played an important role in the further development of weather research. The measured values were no longer exchanged by post couriers between the individual weather stations, but could be mortared to a central weather station. Thanks to this technology, the weather data could be evaluated more quickly and forecasts could be made regarding the weather situation in other parts of Germany or even in Europe. Enormous progress in science, which led to politicians and high military officials recognizing the advantages of weather recording. Of course, the weather also played a decisive role in armed conflicts. They wanted to use this advantage and so it came to the development of the first weather charts in Germany.

Today, weather measurement data from past decades play a far more important role in the field of climate research. Thanks to the data material, climate lounges are able to make targeted statements about climate change. Using statistics, the changes in the weather in the 16 German federal states from 1880 to the present can be precisely assessed. We now know that temperatures in Germany have tended to rise since 1881. It has been proven that temperatures are already one degree higher on average than at that time. This means that climate change can be clearly scientifically substantiated by data from weather records.

When buying a weather station nowadays there is a wide choice and a variety of equipment features. The decision is often not easy. Therefore one should be clear before the purchase of a weather station over it, for which purposes the weather station is to serve later. Do you want a weather station with lighting and a colour display or a station that can provide a weather forecast at the same time? In the following, different models of commercial weather stations are listed:

The story of the weatherman has been going on for a long time! But what is it about the myth and where do the stories and drawings come from? The tree frog has long been regarded as a true weather expert in Germany. According to the story, he sits in a large preserving jar and climbs up or down a small ladder depending on the weather. These climbing insoles are intended to give people an idea of the weather ahead. But it is not only his pleasure in climbing that serves us for the weather forecast. Differences in his skin colour, croaking and laying eggs are also considered, according to legend, as indications of approaching sun or rainfall. But has the myth ever been scientifically investigated or even proven?

Natural scientists have long observed the behaviour of various amphibian species in tropical regions of our planet. They have found that, for example, frogs are significantly more active shortly before the onset of rain and express their changed mood by loud quaking. Then the small animals crawl out of their hiding places in the thicket. It is also noticeable that tropical frog and toad species only lay their hatching eggs in puddles or large puddles. Tadpoles need the wet wet environment to develop successfully. Apparently amphibians know exactly when the best time for reproduction is and approaching rains offer suitable places to lay their eggs.

But is the change in animal behaviour really due to the weather? Do you really feel the changes so clearly? Biologically, toads and frogs must be able to rely on their instincts. This is due to the fact that amphibians are warm and changeable. This means that the animals do not have a body function that can regulate their temperature independently. For this reason, the blood, organs and all muscles of amphibians have the same temperature as the environment in which they live. This miracle of nature is regulated by the special skin structure of the animals, which is traversed by many small glands and therefore reacts very strongly to temperature differences. Frogs and toads secrete their body fluid through the skin glands, which evaporates at the same time. In this amazing function of the body of amphibians lies the reason why they can perceive differences in humidity better than we humans.

But how do our native tree frogs react to weather changes? Why do they climb up trees and bushes in sunshine and warm temperatures and remain sitting on the ground in damp grass during approaching rainfall? Researchers suspect two reasons for the behaviour of our native animals: In contrast to the tropical frog and toad species, the tree frog loves climbing and likes it sunny and warm. In late summer it is not uncommon to see young male frogs on thin branches or leaves sunbathing. However, the search for food also plays a decisive role. This is because tree frogs also use the climbing tours to find food. Insects are the basis of their nutrition. And these creatures, in turn, also react strongly to changes in the weather. Insects fly higher in sunny temperatures and with little wind. On windy, cool days, however, mosquitoes tend to stay on the ground. An interesting phenomenon!
