🌡️💧 Precision sensing that keeps you ahead of the curve!
The AHT10 is a high-precision digital temperature and humidity sensor featuring a state-of-the-art ASIC chip and MEMS capacitive sensing technology. It delivers calibrated digital output via I2C communication, boasting ±0.3°C temperature and ±3% relative humidity accuracy. Its compact 4x5mm SMD package ensures easy integration into diverse applications such as HVAC systems, weather stations, and smart appliances, making it a reliable upgrade over legacy sensors like the DHT11 and SHT20.

Accurate and inexpensive Temperature/Humidity sensor.
I hastily sent a complaint to the vendor of these devices as I could not seem to get them to work with a Raspberry Pi PICO, but it turned out to my fault. Wiring issue and lack of understanding how I2C interfaces work on the PICO. These devices are less expensive and much more accurate than HT11 sensors. They work very well with the PICO using Thonny and micro python.

Definitely better than the DHT22
Switching from the 1-wire DHT22 to the I2C AHT10 was the best move. More reliable readings. Better port to Linux, which is running on my Odroid-C4. I hated Arduino in the first place, but they made the 1-wire easy. Porting to Linux, was simple and what an improvement.

Worked great, but...
These sensors seem to work great, and I love that they don't need to be calibrated. There is however one issue, they do not play well with others on I2C buss. In fact they don't play with others at all, despite having an I2C address, they will not allow other devices on the bus to function. They are complete bus hogs.

As described.
I've used about 1/2 of them and they are functioning perfectly.

Got a bad batch.
7 of 10 did not work.

Work Good. Documentation could be better
They work great once you figure out in espHome that the variant is actually AHT20 not AHT10

3+/10 units faulty within a week of in-service
haven't done a robust failure analysis given the low-cost, but within a week or so of operation have had issues with a plurality of units. one developed a VCC short that was fairly dangerous and damaged an esp32 one made errors on i2c bus one has considerable noise in the sensor signal i also have one that started to develop vcc-short-like symptoms (reporting massive temperature spikes) that i pulled from service until i can take a closer look at it, fwiw. i have one unit left of the 10 that isn't in service yet, will see how that goes. will update review if i do failure analysis on the others, particularly the vcc short. for the low cost, i would not say you shouldn't buy it - just that you'll have to pay again afterwards in watchdog-ing to weed out the bad ones. i needed 8 sensors to complete my project, so i'll likely need to source additional parts since i exhausted my margin from the 10 (i kept the noisy sensor in service for now).

terrible design/ functionality
there is an AHT20 that works properly on the i2c bus. This one does not allow for multiple devices on the i2c
