A rainfall recorder (or rain gauge, rain gauge) is an instrument used by meteorologists and hydrologists to measure the amount of precipitation in an area over a period of time (the measurement of snowfall requires the use of a snow gauge).
common types of rain sensor
According to the different measurement principle of the rain sensor. There are 3 common used types of rain sensor, they are Tipping Bucket Rain Gauge, Piezoelectric Rain Detector sensor, Radar Rain Detector sensor.
What is a Tipping Bucket Rain Gauge ?
Mechanical rain gauge, also known as tipping bucket rain gauge, is a remote measuring rain gauge composed of sensors and signal recorders. , recorder, self-recording clock, control circuit board, etc.

Tipping Bucket Rain Gauge working principle:
How Tipping Bucket Rain Gauge Works ？
Mechanical rain gauge, also known as tipping bucket rain gauge, is a remote measuring rain gauge composed of sensors and signal recorders. , recorder, self-recording clock, control circuit board, etc.
Piezoelectric Rain Detector Working principle:
The piezoelectric rain detector adopts an advanced small piezoelectric sensor module, and uses the technology of the voltage effect generated by the impact of raindrops on the piezoelectric module to measure the intensity of rainfall.
Radar Rain Detector working principle:
How Radar Rain Detector Works ?
The radar rain detector adopts an advanced small flat-panel radar module, and uses 24GHz Doppler radar wave technology to measure the falling speed of rainfall droplets, and can distinguish rain, snow and hail according to the particle size and falling speed of rainfall droplets. type and intensity of rainfall.
Rain sensor application
Rain sensor is suitable for meteorological stations (stations), hydrological stations, agriculture, forestry, national defense and other relevant departments to remotely measure liquid precipitation, precipitation intensity, and precipitation start and end time. For flood control, water supply scheduling, hydrological automatic monitoring and reporting system for power station and reservoir water management, automatic field monitoring and reporting station, it is a precipitation measurement sensor.
