The product uses industrial chips and imported SHT20 high-precision temperature and humidity sensors to ensure the product's excellent reliability, high precision, and interchangeability. With an RS485 hardware interface, the protocol layer is compatible with the industrial standard Modbus-Rtu protocol.
The product integrates the MODBUS protocol and the common protocol. The user can choose - even the communication protocol. The common protocol has an automatic download function (RS485 connection and passing the serial port setting tool will automatically output temperature and humidity).
Product highlights: Industrial product, high progress SHT20 temperature and humidity sensor, RS485 communication;
Standard MODBUS protocol and common protocol are integrated, users can choose the communication protocol themselves;

Baud rate can be set by yourself;
The common protocol has an automatic download function, and the download speed can be set by yourself.
