Product Introduction
The RY-CYX rain and snow sensor is used for qualitative monitoring. The principle is to utilize the conductive properties of rainwater, adopt advanced detection circuits, and use surface grid electrodes to sense external rain and snow conditions, detecting whether there is rain or not in the external environment. The internal adopts imported intelligent microprocessors, which have sensitive response and high measurement accuracy.
After the product upgrade, the output signals are diverse. The rain and snow sensor signal output includes RS485 digital signal and relay switch value (default normally open) signal.

Product Features
1. Small size, easy to install;
2. The gate is treated with gold deposition, which enhances its corrosion resistance;
3. Reasonable structural design, long service life, good sealing performance, up to IP67;
4. Long transmission distance and strong anti-interference ability;
5. The output signals are diverse and can meet different needs;
Scope of Application
Suitable for qualitative measurement of external rain and snow (presence or absence), it can be widely used in the fields of meteorology, oceanography, environment, airports, ports, agricultural greenhouses, and transportation auxiliary measurement.
