Rain Sensor

Telecontrolli Rain Sensor  is made of thick-film technology which has a great reliability both from the mechanical point of view that thermal-electrical. The sensor is made up of three parts: Capacitive sensor, Heat sensor, and Tmperature sensor. On the top side you can find the capacitive sensor. This side part is exposed to the natural agents (rain) while on the bottom side there are the heater generator, the temperature sensor and the connection interface (six pads). The capacitive sensor has a rain sensitive area, which in dry conditions assumes the nominal value. Moreover in presence of the rain, the capacitance goes to high values compared to dry conditions and the ratio changing is over 300%.
