# Temp+Humidity XY-MD02

SHT20/SHT30 series of temperature and humidity sensors are widely used in process and environment monitoring. In this tutorial, we explain a popular instrument which has SHT20 sensor (or similar model) and provides Modbus/RS485 output. 

{% hint style="info" %}
YuDash IoT devices also support SHT sensors through I2C interface for direct reading of sensors without Modbus
