WSLRWEX-RS485 is an Exd LoRaWAN node with an RS485 master port to connect to any sensor, water meter, power meter, gas meter, or flow computer with an RS485 slave port. The device supports different fieldbus protocols like Modbus RTU, Modbus ASCII, DLMS Cosem, and Mbus...The device is configurable via offline software and downlink messages. Ultra-low-power design and smart firmware allow the sensor to run on a C type battery 3.6V for 10 years with one update per day. The sensor will transmit data over kilometers to the LoRaWAN gateway, any brand on the market. It supports all LoRaWAN frequency bands, including EU868, IN865, RU864, KR920, AS923, AS923-2, AU915, and US915.
