Product Description

        The product adopts industrial grade chip and high-precision imported SHT20 temperature and humidity sensor to ensure excellent reliability, high precision and interchangeability. RS485 hardware interface (with lightning protection design), the protocol layer is compatible with the standard industrial Modbus-Rtu protocol. 

        This product integrates MODBUS protocol with common protocol. Users can choose communication protocol by themselves. The common protocol has automatic upload function (connecting RS485 will automatically output temperature and humidity through serial port adjustment tool).
