Good sensor, check wiring
Works great once I realized the SDA and SCL pins were swapped on my specific board. Accuracy seems spot on compared to my calibrated meter.

Much better than DHT11
Finally upgraded my weather station. The I2C interface saves GPIO pins and the readings are much more stable than my old DHT11 sensors.

Reliable data
Been running for 3 months without drift. Great value for the price compared to SHT30 sensors for basic monitoring needs.

Perfect for ESP32 projects
Library support is excellent. Used it for a smart home dashboard and it responds quickly to changes in humidity when cooking.

One DOA
Ordered two, one worked perfectly, the other didn't respond on the bus. Seller replaced it quickly though, so service was good.
Q: Is the sensor itself waterproof?
A: No, only the chip is protected. Do not submerge the module in water or expose it to direct rain.
Q: Is this 3.3V or 5V logic compatible?
A: It supports 2.2V to 5.5V, so it works safely with both 3.3V and 5V microcontrollers without level shifters.
Q: Does it need calibration out of the box?
A: No, each sensor is calibrated at the factory before shipping and is ready to use immediately.
Q: Which library should I use for Arduino?
A: We recommend the Adafruit AHTX0 library or the SparkFun AHT20 library for easy integration.
Q: What is the default I2C address?
A: The default hexadecimal address is 0x38. Please ensure no other device conflicts on this address.
