This product is a rainfall sensor that utilizes infrared optical detection principles to measure rainfall. It employs optical sensing principles internally to measure rainfall, with multiple built-in optical probes ensuring reliable rainfall detection. Unlike traditional mechanical rainfall sensors, optical rainfall sensors are smaller, more sensitive, reliable, intelligent, and easy to maintain. The sensor is extremely sensitive and is not affected by other factors. It can measure rainfall without being impacted by rainwater and can be moved while measuring. There are no exposed parts, so the internal conductors will not corrode due to contact with water. It is completely sealed and will not allow water to enter. It will not affect rainfall measurement due to fallen leaves or other debris.

1. Integrated design, no moving parts, small size, light weight, easy to install.

2. Low power consumption design, saving energy.

3. High reliability, capable of operating normally in high-temperature and high-humidity environments.

4. The design is easy to maintain and not easily obstructed by fallen leaves.   

5. The rainfall is measured using optical detection principles, ensuring accurate measurement.

6. Supports multiple signal outputs, including switch signals and RS485 signals, with flexible configuration options.
