PRODUCT DESCRIPTION
The L301 Optical Rainfall Sensor is a newly developed optical rainfall sensor by Jinzhou Sunshine. It uses an infrared light beam to detect raindrops that come into contact with the outer sensing surface. Compared with a typical tipping-bucket rain gauge, it is 100 times more sensitive, individually counting each raindrop and transmitting the measurements as pulse signals.
The L301 Optical Rainfall Sensor adopts an infrared optical detection principle and contains no mechanical components. As a result, it is more robust, durable, sensitive, and reliable than rain gauges based on other technologies.
The sensor is extremely sensitive and is not affected by external interference. It is immune to the impact of falling raindrops and is capable of measuring rainfall accurately even while in motion. With no exposed parts, the internal conductors are fully protected and will not corrode due to contact with water. The completely sealed structure prevents water ingress. In addition, rainfall measurement is not affected by fallen leaves or other debris.
