The Rainfall Sensor is a remote tipping bucket style rain gauge that measures the amount of liquid precipitation.

The E-822-TR-525I rain gauge is a freestanding receptacle for measuring precipitation. It contains an open top, which allows rainfall to fall into the upper portion, which is called the collector. Collected water is funneled to a mechanical device (tipping bucket), which incrementally measures the rainfall accumulation and causes a momentary closure of a switch. As water is collected, the tipping bucket fills to the point where it tips over. This action empties the bucket in preparation for additional measurement. Water discharged by the tipping bucket passes out of the rain gauge with no need for emptying.

The E-822-TR-525I was designed to meet the need for a rugged and reliable rain gauge tipping bucket with high accuracy and low cost.
