GY-SHT31-D Digital Temperature and Humidity Sensor with I2C

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The GY-SHT31-D is a digital sensor module based on the Sensirion SHT31 sensor. It measures both temperature and relative humidity with high accuracy and is suitable for a wide range of electronics projects and monitoring systems.

The sensor communicates digitally via I2C, making it easy to connect to microcontroller boards such as Arduino, Arduino Mega 2560, ESP32 and ESP8266. Communication requires only two signal wires, SDA and SCL, in addition to power and ground.

The temperature measurement range is from -40 to +125 degrees Celsius. Relative humidity can be measured from 0 to 100 percent RH. The sensor offers a typical temperature accuracy of plus or minus 0.2 degrees Celsius and humidity accuracy of approximately plus or minus 2 percent RH.

The module also features AD and AL connections. AD is used to select the I2C address between 0x44 and 0x45, allowing two SHT31 sensors to share the same I2C bus. AL is a digital alert output that can be activated when programmed temperature or humidity thresholds are exceeded.

The GY-SHT31-D is suitable for climate monitoring, weather stations, ventilation systems, temperature monitoring in electronic enclosures and indoor environmental monitoring.
