🌡️ DHT22 Digital Temperature and Humidity Sensor: Aideepen AM2302 for Arduino - Enhanced Replacement for SHT15 and SHT11 Sensors Review

To be honest, a little more accurate than I expected. As with many things like this, it requires some checking and calibration, but seems very consistent.

i haven't tested it yet but i think it's ok. The sensor is of much better quality than I expected, and while it's not waterproof, it's epoxy sealed and somewhat weather resistant.

Great for what I have in mind. My only concern is temperature accuracy. My BMP180 sensor always shows +1C. It's okay, but I would like to know about sensors.

Works well with Raspberry Pi Zero W I made a temperature monitoring solution for my wife with an instructable post. You can see the graphical data of temperature and humidity in the picture. It matches other sensors I have at home.

DHT22 should support polling every 2 seconds. To be safe, I did this every 5 seconds and still had issues when every 4 or 5 readings it returned "nan", aka Not A Number, instead of the actual temperature and humidity reading. I'm using the Adafruit DHT library for Arduino. Temperature readings are accurate to 1/10th of a degree, so I expected decent accuracy, but it showed slightly high readings compared to several other sensors.

Used for smart home projects with Raspberry Pis and Raspberry Pi Zeros. In general, I am very satisfied with the processing quality and the operation of the device. I've compared it to expensive home weather stations/thermometers and found the accuracy to be within +/- 0.3°C. It's also very easy to set up a Raspberry Pi device - documentation is plentiful, and the manufacturer has labeled the pins correctly too (which unfortunately isn't always the case with other manufacturers).
