The product adopts an 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 a common protocol. Users can choose communication protocol by themselves. The common protocol has an automatic upload function ( connecting RS485 will automatically output temperature and humidity through the serial port adjustment tool ).

Applications:

1. Factory Detect
2. Equipment box Detect
3. Environmental test
4. Home security

Features:

1. Support MODBUS RTUprotocol
2. RS485 supports 1000 meters of communication
3. Standard DIN35 mounting rails
4. High precision
5. Industrial products, high progress SHT20 temperature, and humidity sensor, the RS485 communication
6. Standard MODBUS protocol and ordinary protocol, the user can choose communication protocol
7. Baud rate can decide for themselves
8. General agreement with automatic upload function, upload speed can decide for themselves
