Good sensor, slow shipping
Accuracy is great and integration was easy. Only giving 4 stars because the packaging was slightly dented upon arrival, though the module works fine.

Needs pull-up resistors
Didn't work initially until I added external pull-up resistors to the SDA and SCL lines. Might be obvious for pros, but beginners should be aware.

Stable readings
Compared to cheaper alternatives, this module provides very stable humidity readings without much fluctuation. Worth the extra cost for precision projects.

Perfect for my weather station
Works flawlessly with my ESP32 project. The I2C communication is stable and the readings are much more consistent than my old DHT22 sensors.

Easy to use library
Found plenty of examples online for Arduino. Took me less than 30 minutes to get data logging to an SD card. Highly recommend for beginners.
Q: Can I connect multiple sensors on the same bus?
A: Yes, you can connect multiple sensors provided they support different I2C addresses or you use an I2C multiplexer.
Q: Is there a Python library available for Raspberry Pi?
A: Yes, this sensor is compatible with the Adafruit CircuitPython SHT31 library, which works seamlessly with the SHT30 chip.
Q: What is the default I2C address?
A: The default I2C address is 0x44. Some variants may allow address selection via a pin, but this standard module uses 0x44.
Q: Is the sensor waterproof for outdoor use?
A: The sensor chip itself is not waterproof. For outdoor use, we recommend placing the module inside a breathable weatherproof enclosure.
Q: Does this work with 5V logic microcontrollers?
A: Yes, the module supports a supply voltage range of 3.3V to 5.5V DC, making it compatible with both 3.3V and 5V logic systems.
