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

I'm using this with an ESP12E (ESP8266 development board) to act as a wireless temperature and humidity sensor in the baby's room. I couldn't be happier with the sensor's performance and ease of use, I hope to purchase a few more soon.

Big improvement!Now I see changing Hum values.Temperature much closer.The old 11 was only in the ballpark.Pin compatibility is a GREAT IDEA.Same com protocol is great too.Math is slightly different, check the docs real close. Result: EXCELLENT!

Had it for a month outside in a good enclosure protected from the elements working perfectly. One night it got a little too humid and the sensor failed on me. Be careful as it seems to be too sensitive to moisture for some reason, otherwise worked wonderfully.

I got 2 of these sensors from different sellers and the humidity reading from both was about 20% less than my other devices, including a DHT22 which does work. I tried different wires, pins, resistors, libraries with no change. I even went through the elaborate re calibration procedure in the datasheet. I'm returning it and likely won't bother with this kind of sensor in the future.

Have 2 of them. One reads different than the other for humidity about 5%

Worked great. Good price.

Work great. Better than the DHT11. Next time, I'll go with sensors mounted on a board though so I don't need to add a resistor.

Good price and reliable component
