Good value sensor

Solid sensor for the price. The pins are slightly fragile so be careful when soldering headers.

Good but check voltage

Make sure to use 3.3V logic if possible. Works on 5V but level shifting is recommended for longevity.

Works perfectly with ESP32

Easy to wire up and the library support is excellent. Readings are stable and match my reference meter closely.

5 FAQ

Q: What library should I use for this sensor?

A: The Adafruit SHT31 library is widely used and supports most variants in this series.

Q: What is the default I2C address?

A: The default I2C address is typically 0x44, though some variants may use 0x45 depending on the pin configuration.

Q: Is the sensor waterproof?

A: No, the chip and PCB are not waterproof. Please house it in a ventilated enclosure for outdoor use.

Q: Does this work with a 5V Arduino Uno?

A: Yes, it is compatible with 5V systems, but we recommend using a logic level converter for best reliability.

Q: How fast does it update readings?

A: The typical response time is around 8 seconds for full accuracy, but faster polling modes are available.
