Good accuracy for the price
Compared it with a professional meter and it was very close. Slightly slow to update.

Documentation could be better
The sensor works but finding the exact I2C address took some trial and error.

5 FAQ
Q: Can this sensor be used outdoors?
A: The module itself is not waterproof. Please use a weatherproof enclosure for outdoor use.
Q: Does this require manual calibration?
A: No, each sensor is factory calibrated before shipping.
Q: Is this compatible with 3.3V logic levels?
A: Yes, the module supports voltage from 2.2V to 5.5V, so 3.3V systems are compatible.
Q: What library do you recommend for Arduino?
A: The Adafruit AHTX0 library or the standard Arduino Humidity library works well.
Q: Do I need to buy pull-up resistors separately?
A: Most modules include onboard pull-up resistors. Check the specific board layout image.
