🌟 Elevate Your DIY Game with DHT11!
The DHT11 Temperature and Humidity Sensor Module is a reliable digital sensor designed for precise environmental monitoring. With a temperature range of 0-50°C and humidity range of 20%-95%, it offers excellent accuracy and stability. Ideal for integration with Arduino and Raspberry Pi, this sensor simplifies your projects with its single-wire connection and low power requirements.

works as described in the datasheet...which is not common.
Many datasheets seems to be written to obscure the truth by making it seem like corner conditions with multiple asterisks are the normal operating region of the IC. Not this one. It's simple, easy to deploy on Arduino given the libraries available within the Arduino IDE, and it's pretty accurate for what it is. I plan to use mine for a fermentation chamber control. Time to start ordering cultures for salumi.

These work well, easy to sample with Arduino library
Both of these sensors have worked well for me. I'm using them with an Arduino Every and a Moteino USB. The Arduino dht11 library works well with these. I use the low power library with the Moteino, power them "on" with one of the digital pins, but only for a second or two to take the reading to save power. They give me a reading that is within one degree of a commercial thermometer that I have.

Pretty accurate but inconsistent quality
The accuracy is possibly a little off but as long as they are consistent then I can calibrate. In the screenshot, there is output for two separate sensors. The temps are pretty consistent but I notice that the humidity ranges from about 1 to 2 differently. For the output the sensors were sitting about 2 inches apart. The soldering could use some better consistency. In the photo, you can see that one board is soldered on straight but one is crooked. What a great price ($7.34 at the time) for an accurate temp. The humidity is close enough. I don't really need it so its just a bonus. If you're looking for something with extreme accuracy, I think you'd be looking for something a lot more expensive.

As expected
Works just fine hooked up to my Shelly device for temperature and humidity readings.

it does the job

One DOA and One Inaccurate
One sensor was completely inoperable, DOA. Trouble shooting that wasted an hour of my time. After checking and double checking the wiring and code, tried the second sensor on the same circuit and everything immediately came to life. While the temperature was reasonably accurate, the humidity was off by over 20%. Put the first bad sensor back in the same circuit and no output once again. Yeah, it's bad; case closed.

as advertised & good condition
DHT22 sensors aren't exciting or fancy, but these arrived in good condition in an anti-static pack (nice of them at this price point), both working; I'd recommend this seller if you need these basic sensors for cheap.

One worked one didn't
First one worked perfectly. Noticed that the plastic cover on the bad one has a crack on it. Didn't notice any bad solder joints. I would have swapped them right away but I was setting up the first one at my cabin and forgot the other one at home. A week later when I swapped it with the working one it didn't work. Now how does one return a portion of a multi pack?
