Overview
The G2-RAIN Alert System includes an integrated mo-
dem. Power is provided internally through (2) D-Cell
lithium batteries. An external power cable (optional ac-
cessory) allows connection to an SP-Series solar panel for
recharging the internal batteries and direct communica-
tion (serial to PC). The integrated tipping bucket supplies
accurate rainfall measurements (one tip per 0.01” rain).
Data is accessed and stored on the WQData LIVE web
datacenter. An easy-to-use dashboard and built-in sensor
library automatically facilitate setup and configuration.
