At a glance
Machine status sent over LoRa with up to 8 km line-of-sight range, cutting patrol time and keeping a full equipment history.
This system shows the status of equipment rooms at a glance. Slave units capture signals on licence-free radio bands and send machine status in real time over LoRa to a host unit, which passes the data to the monitoring PC via USB. Inspections take less time and the equipment history is always available.
