Great for Arduino projects
Works perfectly with my ESP32. Library available online makes it easy to integrate into my weather station.

Low power consumption
Ideal for battery-powered weather stations. Sleep mode works well and extends battery life significantly.

Exactly as described
Pins were well soldered. No issues with I2C address detection. Will buy again for future projects.

Good sensor, slow shipping
The module itself is high quality and functions as expected. Shipping took a bit longer than expected though.

Accurate readings
Compared it to a calibrated meter and it was very close. Good value for the price point.
Q: What is the default I2C address?
A: Typically 0x38, but please check the specific datasheet for your variant as it can vary.
Q: Is this compatible with Raspberry Pi?
A: Yes, it works via GPIO I2C pins. Ensure you enable I2C in the raspi-config settings.
Q: Can this be used outdoors directly?
A: The sensor is accurate but should be housed in a protective enclosure for outdoor use to prevent water damage.
Q: Do you provide sample code libraries?
A: Yes, compatible libraries are available for Arduino, PlatformIO, and Python.
Q: Is factory calibration included?
A: Yes, each sensor is factory calibrated. No user calibration is required for general applications.
