SPECIFICATIONS

Product Introduction

The product adopts industrial-grade chips and high-precision imported SHT20 temperature and humidity sensors, ensuring excellent reliability, high precision and interchangeability of the product. This product adopts an RS485 hardware interface (with lightning protection design), and the protocol layer is compatible with the standard industrial MODbus-RTU protocol. It integrates the MODBUS protocol and the common protocol. Users can choose the communication protocol by themselves. The common protocol has an automatic upload function (when connected to RS485, the temperature and humidity will be automatically output through the serial port adjustment tool).
