Perfect for Home Automation
Integrated smoothly with my ESP8266 project. The readings are stable and the I2C library support is excellent. Highly recommend for IoT builds.

Great for Greenhouse
Monitoring my plants easily with this sensor. Humidity readings help me automate the misting system perfectly.

Accurate and Reliable
Tested against a calibrated professional meter and the variance was negligible. Great value for the price point.

Good Module
Works well but please note headers are not included. Had to solder my own pins. Otherwise, performance is solid.

Easy to Use
Library examples worked out of the box with Arduino. Setup took less than 10 minutes. Very satisfied.
Q: What is the default I2C address?
A: The default I2C address is 0x44. It can be changed to 0x45 by bridging the address select pad on the PCB.
Q: Can this sensor be used outdoors?
A: The sensor itself is robust, but the PCB is not waterproof. We recommend using a breathable enclosure for outdoor applications.
Q: Which library do you recommend?
A: We recommend the Adafruit SHT31 library, as it is fully compatible with the SHT30 sensor chip.
Q: What is the maximum cable length for I2C?
A: For reliable communication, keep the I2C cable length under 30cm. Use shielded cables for longer distances.
Q: Is this compatible with Arduino Uno?
A: Yes, this module is fully compatible with Arduino Uno. You can use standard I2C libraries to interface with it.
