The G.Force Wireless Full Bin Alarm is designed to provide the ultimate in convenience and safety to perform tasks remotely. It is a radio frequency (RF) sensing device that helps prevent overfilling of grain bins by activating an alarm when the grain Sensor Probe is activated. The Sensor Probe, which operates at 418 MHz FM, transmits securely encoded information to the Receiver, which then decodes the information and alerts the user that the bin is full. The Sensor Probe and Receiver are designed to operate within 300' but actual range is dependent on operating environment.
