Optical rain sensor – Rainfall monitoring

 Product Introduction

Optical rain sensors measure rainfall using the principle of optical sensing. Using infrared light as the measurement medium, multiple optical probes are built-in. Avoid external light and fog and water to interfere with the detection of the optical rain sensor, making the measurement results more accurate. Compared with traditional mechanical sensors, optical rainfall is small in size and high in sensitivity. It is an intelligent and easy-to-maintain weather monitoring device.

Compared with the tipping bucket rain gauge: the optical rain gauge is small in size, simple to install, and easy to maintain. The optical rain gauge uses electronic optics and a series of microelectronic filtering, amplification, and detection technologies. This principle has the advantage of sensitivity. During installation, because the optical rain gauge is non-mechanical and non-contact measurement, there is no horizontal installation requirement, so the installation is simple and the subsequent maintenance is also convenient. The shell has smooth lines and an easy-to-maintain design, which is not easily blocked by fallen leaves.

Optical rain sensors Features

1. All-solid-state integrated design, beautiful appearance;
2. The impact measurement principle is used to calculate the weight of a single raindrop, and then calculate the rainfall;
3. No mechanical parts, no exposed parts, put an end to leaves, dust, bugs;
4. High measuring accuracy, wide range, good stability, low power consumption, strong ability to resist external interference;
5. Rain sensor can work all day, not affected by weather changes, accurate to second rainfall monitoring;
6. The shell of the rain sensor is maintenance-free, the raindrop contact surface is curved design structure, no rainwater storage;
7. The sensor with automatic horizontal calibration function after installation, no on-site calibration;
8. The sensor is compact in size, easy to carry, disassemble and install.
