Easy to integrate
Library support is excellent for both Arduino and Python. Got it running in less than 10 minutes. Highly recommend for beginners.

Compact and reliable
Used it for a terrarium monitoring project. The small form factor fits perfectly inside the enclosure without taking up much space.

Great value
Shipping was fast and the sensor works well within the specified voltage range. Documentation could be slightly better but overall satisfied.

Good accuracy
Readings match my professional meter closely. Only giving 4 stars because the header pins were slightly loose upon arrival, but easy to solder.

Perfect for my weather station
Works flawlessly with my ESP32 project. The readings are stable and the I2C connection was easy to set up using standard libraries.
Q: Can I use 5V logic levels directly?
A: Yes, the module supports a wide voltage range from 3.3V to 5V, so it is compatible with 5V logic microcontrollers.
Q: What is the default I2C address?
A: The default I2C address is typically 0x44, but please check the specific datasheet for the variant you received as it can vary.
Q: Does it need calibration before use?
A: No, each sensor is factory calibrated. You can start reading data immediately after connecting it to your microcontroller.
Q: What library should I use for Arduino?
A: We recommend the Adafruit SHT31 Library or the Sensirion Arduino Core Software, both are widely supported and easy to use.
Q: Is this sensor waterproof?
A: No, the chip itself is not waterproof. It should be used in dry environments or housed in a breathable protective enclosure.
