Have this sensor running with a raspberry pi 5. I find the values are within 1-2% in temperature and humidity compared with the values from my aranet4, I'm actually impressed.The python software available online to interface with the device is easy to use. Haven't had issues with it so far.

I ended up buying two different temp / humidity sensors on Amazon. The first one, a sensor sold by WWZMDiB on Amazon (the one on the left in the picture) worked out fine for my ESP 8266 project, but the humidity readings seemed to be about 5% off compared to my "Airthings" radon/humidity/temp readings. The HiLetgo DHT22 in contrast gave me readings that exactly matched my "Airthings" and another table top temp / humidity device. I don't have any way to prove which one was right other than thinking if 3 devices agree, I have a better chance of being close to the actual value.You can see in the picture that the HiLetgo is just neater. The plastic enclosure around the sensor just looks crisp on the HiLetgo, but not quite as good on the other. Solder joints were just a tad cleaner on the HiLetgo. The HiLetgo was about twice the price, but I think it is worth paying a little more for a sensor that I am more confident in using. Both units came with hookup wire which made connecting them to the ESP 8266 a breeze. Both claim the same specs on accuracy. The "WWZMDiB" was cheaper and performed okay, just seemed to be a step down from the HiLetgo.

I have to rate this as one star because this sensor did not work.This was supposed to be used to control a relay for a small cooling fan with my Arduino Mega, however, the DHT22 was DOA. The plastic shield is so flimsily mounted to the board that I think it could have been damaged in transit (although it was well packaged), or damaged during hook up. I used the correct libraries and testing code, but continually received "DHT22 Not Found" messages. I also ensured my wiring was correct. I would have loved to give this a higher rating, but I had to put the project on hold until I figure out another alternative.

Not much to say here, these sensors work as advertised and as far as I can tell they are pretty accurate.

Very easy to set up basically plug in and play with the 3 prongs it has, code for it is pretty straightforward too and humidity jumps a bit to much though. for the money it's a great choice

Once the sensors are warmed up and steady state (~5 min) they agree on the same temperature. This is exactly what I needed, and the DHT11s they replaced had errors of 3-5 degrees Fahrenheit.I have been consistently pleased with HiLetgo's quality, and am very pleased with these sensors.

Bought this for use in my Flipper Zero. Both worked fine. They take a few minutes to settle down to the temperature & humidity, but I found them to be accurate. Awesome way to get started into the world of GPIO pins & gadgets etc.

I'm a little new to the world of ESP and this was my first attempt to add something to my Atom Lites. But boy was it easy. I connected 3 Dupont wires from this to 5V, GND, and a GPIO pin on the Atom and was off to the races. Just added a handful of lines of YAML to ESPHome on Home Assistant and the sensors were created. Literally a 5 minute thing, plug and play - no resistor.In terms of accuracy, I have this and a Govee BLE an inch apart on my desk for a few hours and the Govee says 70.9 F and this is putting out 70.9 F. Govee humidity is 38% and this is 39%. If they aren't accurate, well they are identically inaccurate - and I think that is unlikely.Certainly you can find alternatives for a few dollars less, but I wanted no fussing and this delivered.

Item highly recommended I brought this item for my friend as he wanted something that he could control the temp and the humidity of a enclosure for his pet snake, so I built this that controls the heating Matt and the water level so it stays constant
