Grinder Pump Alarm for Low Pressure Sewer Monitoring

The GPG remotes use a 900MHZ ISM band radio mesh network to communicate. Each GPG remote functions as a repeater and has a range of between 500 feet and half-mile depending on terrain and vegetation density. The collector also polls every remote once per hour to verify that they have power and are functioning normally.
