RY-CYX capacitive rain sensor
The capacitive rain sensor(Also Known as Rain and Snow Sensors) utilizes the conductive properties of rainwater through a surface-tin-plated annular curve to achieve qualitative detection of rain and snow in the environment. Equipped with an imported intelligent microprocessor, it offers high sensitivity and precision. An integrated automatic heating device eliminates interference from rain and snow accumulation, ensuring reliable system operation. It outputs a set of normally open and normally closed switch signals for convenient installation and use. This product is widely applicable for qualitative rain and snow measurement in meteorology, oceanography, environmental monitoring, airports, ports, laboratories, industry, agriculture, and transportation sectors.

Introduct
The capacitive rain sensor is designed for qualitative monitoring. Its principle utilizes the conductive properties of rainwater through an advanced detection circuit. Surface grid electrodes sense external rain/snow conditions, detecting the presence of precipitation in the environment. An imported intelligent microprocessor ensures responsive operation and high measurement accuracy. Following product upgrades, output signals have diversified. The sensor now provides: RS485 digital signals and relay switch signals (default normally open).
Structure of RY-CYX Snow and Rainfall Sensor
- Sensing Probe (Sensing Surface): Mostly made of tinned or stainless steel electrodes, used to sense changes in conductivity due to rain and snow or the accumulation of precipitation.
- Signal Processing Unit: Built-in microprocessor for amplifying, filtering, and processing the collected signals.
- Heating Module: Used to melt rain and snow, prevent icing and water film residue, and improve detection stability.
- Output Interface Module: Provides signal output methods such as RS485 and relay switch signals.
- Power Supply Module: Supports DC power supply and provides voltage regulation and protection.
- Protective Casing and Mounting Structure: Waterproof and corrosion-resistant, suitable for long-term outdoor installation and use.

During installation, maintain a 15-degree angle between the sensor’s sensing surface and the horizontal plane to prevent rain or snow accumulation from affecting measurement accuracy.
