environmental controls
I used this with Arduino for environmental control. I added 6′ to the leads and it does not seem to alter the readings. I’ve been using this sensor for about 3 months without any issues. I’ve compared readings with stand alone units and it seems to be pretty accurate.

A fantastic little sensor
A fantastic little sensor. Working great using Adafruit’s python library. It’s pretty slow though (refreshes every couple of seconds) so keep that in mind.

Hard to program
Programming it for Raspberry pi0 use took a while to figure out. The Adafruit_DHT library installs for python version 2 but not python3. You have to run “sudo python3 setup.py install” . Otherwise import Adafruit_DHT gives you “No module named Adafruit_DHT” error. I Googled the error and saw that many people had the same issue.

Works with Arduino Uno
Does not work with NodeMCU.

Not functional
I purchased two. One is flaky and one does not function at all. Returning

Used for 2 months, incorrect reading
Purchased while back for a personal project and have used it for 2 months now. The temperature reading is correct, but the humidity value was off since the beginning, now it keeps reading 99%.

It works
I have this sampling temperature and humidity every minute in my wine cellar using a raspberry pi 3 and some custom python code. I have it uploading to an AWS database (DynamoDB) and built a basic AWS Lambda function so Alexa can give me the current status. Useful and fun little project made possible by this inexpensive device.

Works well
I replaced a TMP36 temperature sensor last night with this unit, and the smoothness of the graph and accuracy is much improved! The casing seems solid too, and could probably take a few knocks.
