If the sensor plate comes into contact with rain or slushy snow/hail, it switches on a relay.

This allows you to retract awnings, close skylights or acknowledge that it's raining.

• The automatically heated sensor surface prevents any freezing or wetting of the sensor surface.
• 2 built-in LEDS indicate the function.
• Waterproof encapsulated electronics.

Note: The electronics of the rain sensor reacts to the electrical conductivity of the water. Now we have found that there are areas where absolutely uncontaminated rainwater falls (distilled water). The sensor does not respond to it. The rain must have a slight amount of contamination (dust particles, smoke, etc. ), so that the water is electrically conductive and triggers the sensor. In 99% of the areas in Germany, the rainwater is conductive. If the sensor does not work for you, please install it so that the rain water runs off a small canopy or something else before the water comes into contact with the sensor. If the water falls directly from the cloud in its purest form on to the sensor and it is not triggered, then it is sufficient, if the water runs onto the sensor via a small board or from a canopy. Then the water will have absorbed enough contamination to be electrically conductive and to trigger the sensor. Of course, install the sensor at an angle so that the water runs of it.
