LoRaWAN Rainfall Sensor

The LoRaWAN rainfall sensor is a hydrological and meteorological instrument used to measure natural rainfall, rainfall intensity, rainfall duration, etc. Rainwater flows into the tipping bucket through the receiver. When a certain amount of rainwater accumulates in the tipping bucket, the funnel tips, emptying the water inside, and the tipping bucket begins collecting water again. Each tipping action of the bucket is converted into a pulse signal (1 pulse = 0.2mm rainfall) via a reed switch and transmitted to the acquisition system. The LoRaWAN rainfall sensor uploads data to the cloud platform in real-time via LoRa base stations to meet the needs of information transmission, processing, recording, and display.
