iGRAIN Network System
Wireless Grain Monitoring via Radiohub
The iGRAIN Temperature Monitoring System is modular in its design and can be configured to small or big silo installations according to the need.
The iGRAIN Master-Radiohub can connect to a maximum of 32 Sub-Hubs. iGRAIN Sub-Hub has 6 inputs for 6 temperature Sensor Cables or moisture sensor cables.
The Wireless Grain Monitoring System can literally be configured to suit any number of grain bin with any number of Sensor Cables. The Master-Radiohub has a build-in display that displays continuously how many Sub-Hubs, Sensor Cables and Sensors it is communicating with. This makes it the preferred system in the industry because the system can be monitored, operated, commissioned and serviced without the need to connect a PC.
