    I am very happy with this so far. It works well with my ESP32S (ESP-WROOM-32) using I2C. My only complaint is the color of the wires. The SCL connection is on the white wire, the GND connection is on the yellow wire, the SDA connection is on the red wire, and the VDD connection is on the black wire. I really wish the ground was black and the VDD was red. So far I have tried the SparkFun library for the AHT20 and the Seeed Studio driver for the BMP280. Each of those libraries are easy to use, and their only dependencies are the standard Arduino libraries. The sensors are two discrete devices on this chip, using addresses 0x38 and 0x77. I have not verified which sensor is at which address because the libraries I am using do not require me to set the address. The BMP280 reads about 1.6°C higher than the AHT20 reads. I have not calibrated these against any other sensors.

    purchased this temperature sensor to use with my M5 stamp pico for my project. It works great and the temperature sensor is good quality and very accurate,which is what I needed it for. 👍
