The product adopts industrial grade chip, high-precision imported SHT40 temperature and humidity sensor to ensure the excellent reliability, high precision and interchangeability of the product. Using RS485 hardware interface (with lightning protection design), the protocol layer is compatible with standard industrial Modbus-Rtu protocol. This product integrates the MODBUS protocol and the common protocol. The user can choose the communication protocol. The common protocol has an automatic upload function (connecting RS485 through the serial port adjustment tool will automatically output temperature and humidity).
