Review on 4PCS Geekstory DHT22 AM2302 Digital Temperature Humidity Sensor Module - Monitor Temperature and Humidity Levels, Perfect Replacement for SHT11 SHT15, Ideal for Arduino Raspberry Pi by Mike Ogunlana
All four differ in temperature
Comes in a pack of four. I connected each of them to the same device and with the same software, three differed by +/- 5 degrees, one was more than 40 degrees lower than the others.
- AM2302 sensor can work on either 3.3v or 5v
- Definitely a bad product
