Use LoRa wireless RF tranceiver modules as alternative to RS485 cable and save trenching, conduit and cable cost for long distance. The modules will work as a bridge between sensors and datalogger.
The LoRa Data Transmission Terminal, Model IOT-L2S-B1&B2, is a universal communication interactive equipment which is designed and manufactured based on LoRa RF chip. It integrates two interfaces of industrial standard RS485 and supports a variety of protocols to realize the data transmission between wired and wireless devices. It can be widely applied in the IOT, centralized metering and industrial control etc.
2 standard interfaces of RS485, supporting a variety of protocols including Modbus RTU and communicating with various automatic devices with RS485 interfaces equipped LoRa chips SX1278 from Semtech for RF part
