    The NETVOX LoRaWAN wireless seat sensor (two way) R311WA is a device that detects the presence of a seat and is compatible with the LoRaWAN protocol. If there is someone on the seat, R311WA will send a message to the gateway. When detecting no one on a sensor seat, it will send a normal status message back to the gateway.
