LoRaWAN Rainfall Sensor

The LoRaWAN rainfall sensor is a hydrological and meteorological instrument used to measure natural rainfall, rainfall intensity, and rainfall duration. Rainwater flows into a tipping bucket through the receiver. When a certain amount of rainwater accumulates, the bucket tips, emptying the water, and then begins collecting again. Each tipping action 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 in real-time to the cloud platform through LoRa base stations to meet the needs of information transmission, processing, recording, and display.
