SNOW AND ICE SENSOR WITH A HEATING RESISTOR FOR GROUND INSTALLATION ECOA901
(FIGURE 4)
The sensor is equipped with a heating element which melts ice and snow gathered on the sensor. Addi-
tionally, the sensor has an NTC resistor to measure the sensor surface temperature as well as two metal
rings as humidity sensors.
