5 FAQ

Q: Is the sensor waterproof for outdoor use?

A: The sensor chip itself is not waterproof. We recommend using a breathable membrane or enclosure for outdoor protection.

Q: Can I change the I²C address?

A: The address is typically fixed at 0x44 or 0x45 depending on the specific chip variant and ADDR pin configuration.

Q: What is the maximum sampling rate?

A: The sampling rate is configurable, typically ranging from 1Hz to 10Hz depending on the resolution mode selected.

Q: Is this module safe to use with 5V logic?

A: Yes, the module supports a wide voltage range from 2.4V to 5.5V, making it safe for 5V systems.

Q: Which Arduino library do you recommend?

A: The Adafruit SHT31 library or the Sensirion official library works well with this module.
