2pcs DHT22/AM2302 Digital Temperature and Humidity Sensor Module Temperature Humidity Monitor Sensor Replace SHT11 SHT15 for Arduino Electronic Practice DIY

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.

Lo utilice para controlar la temperatura del corral de los perros recién nacidos con un ESP32 e hice varias comprobaciones con termómetros análogos y era Super preciso, al igual que la humedad relativa del aire.

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.

Mine are surprisingly accurate, and also consistent with each other on a sensor project I made. I had to throw out one from another brand. Once you find one that works, you stick with it and I plan to order more of these.

Exactly what I needed for a project. They look decent, and shipped with the external wires for hookup as well! (and fit my breadboard;-)

These are poorly made. The first one failed within a day. The second one was working for a month or so. The code we are using hasn't changed. Very disappointing.

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?

I used this DTH11 with an ESP-01 WiFi chip running Tasmota software and it was recognize immediately. Tasmota figures the dewpoint and displays that too. The temperature was off by almost 2 degrees but Tasmota allows correction easily with a console command..
