5 FAQ

Q: What is the I²C address?

A: The default I²C address is typically 0x38 for this sensor module.

Q: Can I use this outdoors?

A: The module itself is not waterproof. You need to place it in a protective enclosure.

Q: Is calibration required?

A: They are factory calibrated, so no user calibration is needed before use.

Q: Is this 3.3V or 5V logic compatible?

A: It supports 1.8V to 5.5V, so both 3.3V and 5V logic levels work fine.

Q: Does it come with a library?

A: No, but it is compatible with standard AHT20 and AHT21 Arduino libraries.
