Aideepen DHT22/AM2302 Digital Temperature and Humidity Sensor Replace SHT11 SHT15

If you own a DH11 you need to change ro this version, you want be disappointed. DH22 is after, energy efficient, and completely compatible.

Using this for a "smarthome" project with Raspberry Pis and Raspberry Pi Zeros. Overall very satisfied with the quality of the manufacture and the performance of the unit. I've benchmarked it against costly home weather station units/thermometers, and the accuracy is there within +/- 0.3 C in my observation. Very easy to set up with the Raspberry Pi unit as well - plenty of documentation is out there, and the manufacturer has also labelled the pins correctly (which, unfortunately, doesn't always happen with other makers...)

Works great for what I intended.My only issue with it is the accuracy of the temperature. It consistently reads about +1C over my BMP180 sensor. Not a big deal, but I'd is something to be aware of with sensors.

Product was received as described; new and in the box. Looking forward to using it on my project.

Quite a bit more accurate than I expected, to be honest. Like many such things, it takes some checking and calibration, but it seems to be very consistent.
