Snow And Rain Sensors And Controllers
The rain and snow sensor uses the conductive characteristics of rain, adopts advanced detection circuit, and the surface grid electrode senses the external rain and snow situation to detect whether there is rain and snow. The internal use of imported intelligent microprocessor has sensitive response and high measurement accuracy. The built-in automatic heating device can eliminate the interference of rain and snow adhesion and ensure the normal operation of the system. After upgrading, the output signals are various, including analog signal (voltage and current), digital signal RS485, relay switching value (default normally open) and NPN.
