XY-MD02 Temperature and Humidity Transmitter SHT20 Sensor Modbus RS485

XY-MD02 Temperature and Humidity Transmitter SHT20 Sensor Modbus RS485

The XY-MD02 adopts an **industrial-grade chip** and a **high-precision imported SHT20 temperature and humidity sensor**, ensuring **excellent reliability, high precision, and interchangeability**. It uses an **RS485 hardware interface** with **lightning protection design**, and the protocol layer is compatible with the **standard industrial Modbus-RTU protocol**. This sensor integrates both **MODBUS and common protocols**, allowing users to select the communication protocol, with an **automatic upload function** available when using the common protocol.

Ideal for **factory monitoring, equipment box detection, environmental testing, and home security**, this industrial sensor supports **long-distance RS485 communication (up to 1000 meters)**, comes with **DIN35 standard mounting rails**, and offers **high precision** with a temperature resolution of **0.1°C** and accuracy of **±0.5°C**. Users can also configure the **communication address and baud rate** as required, providing flexible and reliable operation in industrial environments.
