WWZMDiB 3Pcs DHT22/AM2302 Digital Temperature and Humidity Sensor Module Temperature Measure-40-80℃（±0.5℃） Humidity Measure 0%-100% RH（±2%） for Arduino DIY

I have well over 10 of these deployed now and they all work well. Just keep in mind they are not weather proof and should be shielded from sun/rain/snow.

Not a bad deal on DHT22's.

DHT22 is connected to the board with some pretty thin pins, so be careful of bending/breaking those. Otherwise a good product. Integrated pull-up resistor on the data line saves wiring in your project, too.

After my first DHT died, I researched and found that they don't have long lives without turning on and off the power supply between samples so the code and wiring for the usage of this product is a lot more complex than implied by the Arduino sample designs.

These sensors are really easy to use with an Arduino.Took maybe 5 minutes to integrate it in to a larger sketch.I can definitely recommend them!

I'm not and expert at this stuff but I tried my best - the readings frequently drop off to really low states. Bought a higher quality DHT-22 and it physically looks different and has much higher accuracy. Move along, these aren't worth your time

Took off only one star because it might be my fault. If the length of cable you use is too long they seem to freeze or stop sending data.

I have ordered a total of 9 of these sensors in the last few months. So far 3 actually worked. I'm gonna stick with the DHT11's. They always seem to work fine.
