The Master-Hub and Sub-Hub are wiring boxes used to collect data from digital temperature or moisture cables and send it to the Crop-Protector™ software. Use of these rugged boxes enables modular system design scalable for both small and large grain storage operations. The Sub-Hub has 6 inputs for temperature or moisture cables, while the Master-Hub can connect to a maximum of 32 Sub-Hubs. The Master-Hub features a built-in display that continuously shows the numbers of Sub-Hubs, sensor cables, and sensors connected to it. The Master-Hub design allows the system to be commissioned, monitored, and serviced without connecting to a PC, if that is necessary. Most operations choose to interface their system with the Crop-Protector™ Dashboard Manager on a PC or in the Cloud.
