## Customer Reviews

### ⭐⭐⭐⭐⭐ Accurate
*by D***D on May 14, 2025*

No issues, checked it against a digital thermometer and a home weather station and the sensor is spot on.

### ⭐⭐⭐⭐⭐ Very consistent outputs between three devices.
*by B***T on June 10, 2025*

Picture shows a Grafana plot of three of them running within a few feet of each other over the course of about 50 minutes. I don't know how good the absolute accuracy is, but they seem very consistent. Dewpoint is calculated from humidity and temperature according to the Magnus formula. The sensor appears to be an AM2302. BE VERY CAREFUL swapping devices from different manufacturers. If you hold them with the sensor packages facing you and the pins down, some are + OUT - (or VCC OUT GND) and some are - OUT + (or GND OUT VCC).

### ⭐⭐⭐⭐⭐ This is the one to get
*by O***Y on August 11, 2024*

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.
