WSLRW-C-MB is a LoRaWAN compact node with an RS485 Modbus master port to connect to any sensor, water meter, power meter, gas meter, or flow computer with an RS485 slave port. The device supports Modbus RTU protocol. The device is configurable via offline software and downlink messages. It is powered by external power supply. The sensor will transmit data over kilometers to the LoRaWAN gateway, any brand on the market. It supports all LoRaWAN frequency bands.

For Applications
