Using industrial grade chips, high-precision imported SHT20 temperature and humidity sensor ensures excellent reliability, high precision and interchangeability.
Adopt RS485 hardware interface (with lightning protection design), the protocol layer is compatible with standard
industrial Modbus-RTU protocol. This product integrates MODBUS protocol and 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 debugging tool).
