100.053 Small Rain Sensor with Tipping Bucket Technology

Description

The most economical solution

It is a small and functional rain gauge that measures the amount of rain that has fallen using a tilting, automatic emptying bucket. It has a reed switch that opens every time the weight of the accumulated water tilts the spoon, which produces a pulse that can be recorded using a datalogger or pulse counter. It is made of UV- and frost-resistant plastic.

Patented automatic emptying system

A magnet keeps the spoon in a balanced position, so that emptying occurs through a rapid movement of the tip, which immediately returns to the initial position to collect a new portion of water.
