Optical Rain Gauge
An integrated optical rain gauge that automatically senses water hitting its outside surface and provides tip measurement.
Algorithms in the GMX541 interpret this data and simulate the output of a tipping bucket rain gauge as part of the serial output from the GMX541. The optical rain gauge has no moving parts associated with tipping bucket gauges.
Output and power to the GMX541 is via a 20m cable (included) that the user can cut to length.
