Connecting the Rainwise rain gauge

Forums:

The RAINEW 111 Wired Rain Gauge has an 8" diameter collector which meets NWS specifications for statistical accuracy. It can be purchased from Rainman Weather for $65.66.

The gauge provides a dry contact (a reed switch tripped by a magnet on the bucket). This can be wired to a digital input, such as one of the GPIO pins on the Pi (untested) or a device like the Phidget Interface Kit which provides 2 digital inputs, 2 analog inputs, and 2 digital outputs. The Phidget software has been modified to write the number of transitions to a file so the hivetool scripts can pick it up, log it graph it.
