Where do I put the sensors of my weather station?
The temperature is measured with help of a thermometer. For a perfect reading, you need to install the sensor in the shade, at least 1.25 meters above the ground. Make sure the sensor isn't located between any trees or bushes. Sufficient air needs to flow past the sensor. A black surface, such as asphalt, also negatively affects the reading because it holds on to heat for a longer period of time. As a result the reading might be off up to 5 or 6 degrees.
A rain gauge, also called a pluviometer, registers the amount of rain that has fallen in liters per square meter. In order to accurately register the amount of liquid precipitation, you need to place the rain gauge in an open environment. Install the rain gauge in your garden or on your roof, as long as there are no walls or trees nearby that can block the rain. You also need to make sure that the collected rain can also easily exit the rain gauge.
The wind force and wind direction are measured by a wind gauge, also known as an anemometer. You should install the wind gauge in a place that contain a minimum amount of obstacles. A large open field, for example. Seeing as not everyone lives in countryside, a roof is also perfectly adequate. When installing the wind gauge, make sure the weather vane is pointing North. This'll provide your wind gauge with a starting point. Don't own a compass? Don't worry, you can find one on your smartphone.
Humidity, air pressure, and UV radiation
In order to measure humidity, air pressure, and UV radiation, you need different types of sensors. Humidity is measured with a hygrometer, air pressure is measured with a barometer, and UV radiation is measured with a UV meter. These sensors are integrated other sensors. As long as you make sure the temperature, rain, and wind sensors are installed in the right locations, the additional sensors will automatically perform their jobs.
