Review Image by Outdoors guy Outdoors guy
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. ... show more

    • Accurate and easy with ESPHome and an Atom Lite
Size: 2 Count (Pack of 1)
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. ... show more

    • Works perfectly, but the included wires are just pointless.
Size: 2 Count (Pack of 1)
It works. It provides temperature and humidity readings quite accurately and within seconds. However, the included F-F wires are absolutely horrible. They refuse to have anything inserted into them without putting an obscene amount of force into them, to the point the male connectors got bent. not only that, but they don't stay in. But I didn't buy the product for the included cable. It would be nice if the cable wasn't actually worthless. Which sucks, because providing some cable that didn’t suck is quite literally the easiest way for them to improve the product without actually increasing their costs because ain’t no way fixing that would cost them anything more than maybe 1 cent per unit. ... show more

    • Works great with ESPHome

Wanted to set up some temperature sensors in various rooms of the house for Home Assistant. These worked great! I don't have some known good thing to benchmark them against, but they all seem to agree with my perception every time I've checked them. Will probably get some more for other rooms!

    • Cheap sensor that gets the job done.
Size: 2 Count (Pack of 1)
I bought these to wire to a an ESP8266 in an attempt to monitor the temp in my grow tent. It took me 2 days to get it working. I thought my code was messed up. Everything I read said to tap into the 3.3v lead. I finally found out the sensor wasn't working because it wasn't getting enough power. Switched over to the 5v lead and it worked fine. I'll probably make a weather station with the other one. ... show more

    • Accurate and reliable.
Size: 2 Count (Pack of 1)
I've purchased a similarly labeled sensor from a different company only to find that it was not accurate, at all. This version seems more legitimate; the sensor has the part number etched in it and overall has a higher quality build feel to it.

    • Simple setup with Raspberry Pi 2 and 3
Size: 2 Count (Pack of 1)
I bought a pair of these. One went onto a Raspberry Pi 3 with Buster, and an older Raspberry Pi 2 with Wheezy. This DHT22 comes with the resistor already set, so you just need 3 pins to deal with: VCC, Ground and Data. Setup for Buster is pretty straight forward. Just make sure you have python3 installed and pip3 install the adafruit library. For Wheezy, getting pip3 to install is a hassle, skip it, and just git clone the adafruit library instead and use their sample code with the default python to get things running. Both sensors seem to track pretty accurately, and there is very little variance between readings on both temperature and humidity. Been running these for a day now, and am pretty pleased with the results so far. ... show more

    • Easy to use and a great value
Size: 2 Count (Pack of 1)
I got these because they are a good price for two ready to use modules. Only 3 wires, a little bit of code and I've got whatever these say the temperature and humidity are! I have no way to measure their accuracy, but they are responsive in the typical DHT22 fashion (not fast, but consistent results). I will say that both are within 0.5 degree Fahrenheit and less than 1% humidity of each other. Since I only display full degrees and full percentage on my LCD, the slight discrepancy between the two is rarely seen. I will purchase more of these from HiLegto when I am in need of more of these sensors! ... show more
