Frequently Asked Questions

Q: Is the SHT31 sensor module compatible with Arduino boards?

A: Yes! The SHT31/SHT30 breakout module is fully compatible with Arduino (Uno, Nano, Mega, etc.) and works with widely available Arduino libraries such as the Adafruit SHT31 library. Simply connect the SDA and SCL pins to your Arduino's I2C interface and upload a sketch to begin reading temperature and humidity data.

Q: What voltage levels does this sensor module support?

A: This module is designed to work with both 3.3V and 5V systems, making it compatible with a wide range of microcontrollers and development boards including Arduino, Raspberry Pi, ESP8266, and ESP32 without the need for additional level shifters.

Q: What is the difference between SHT30 and SHT31?

A: Both are high-quality temperature and humidity sensors from Sensirion. The SHT31 offers slightly higher accuracy and better repeatability compared to the SHT30, but both use the same I2C communication protocol and are pin-compatible, making this breakout module versatile for a range of weather station and environmental monitoring projects.
