A precipitation sensor or a rain gauge measures the amount of precipitation that has fallen in a time interval. If the precipitation sensor has a built-in heater, solid precipitation such as snow, hail or sleet can be measured and the sensor can be kept frost-free and functional even at low temperatures.


Precipitation sensors are available in analogue and digital device variations and with different measuring principles.
