The capacitive rain sensor detects with precision and effectiveness the precipitation rate, the current precipitation intensity and its end, avoiding false positives which can cause inappropriate operations (objects such as dirt or other particles that in preexisting optical sensors cause a reflection mimicking the one of rain and limit its effectiveness in rapidly responding to light rain).
The Telecontrolli capacitive rain sensor shows higher levels of sensitivity and reliability (it is able to detect light rain, fog and humidity) and noise immunity than other sensors on the market; it takes up a small size (about 35 x 30 x 0.7 mm), his power comsumption is next to zero (it’s a passive sensor) and it is economically competitive on the market.
The ceramic substrate (Alumina) together with the glass layer make the sensor immune to water and moisture absorption, ensuring high resistance and long duration.
The incorporated and configurable heater ensures that the sensor's detection surface dries quickly, protecting the surface from fog, condensed moisture and frost. It also can be disabled when power consumption is critical.
