Optical rainfall sensor: can be widely used in industries such as meteorology, agriculture, municipal engineering, transportation, etc

1、 Product Introduction
The G1 optical rainfall sensor adopts a three channel narrowband infrared detector and a pure sine AC signal source, which has the advantages of high accuracy, strong resistance to environmental light, maintenance free, and compatibility with other optical sensors (light, ultraviolet radiation, total radiation). It can be widely used in meteorology, agriculture, municipal, transportation and other industries. This sensor adopts a low-power design and can be applied to unmanned observation stations in the field.
2、 Product Features
This optical rainfall sensor adopts a pure sine infrared light source, built-in narrowband filter, and a rain sensing surface of 78 square centimeters, which can measure rainfall with high accuracy and is not affected by high-intensity sunlight and other light. The high transmittance rain cover does not affect direct sunlight and is compatible with other built-in optical sensors such as lighting, total radiation, UV sensors, etc.

4、 Precautions
1. There is no obstruction within a 1-meter radius around the sensor to avoid the impact of water droplets splashing
2. The installation position of the sensor should avoid being obstructed by trees, and the tilt direction should also avoid being obstructed by tree shade
To ensure measurement accuracy, the sensor should be installed horizontally
