ICStation.com DHT22 Temperature and Humidity Sensor
In this video we take a look at the DHT22 temperature and humidty sensor. This is the 3rd unit of the DHT line including the DHT11 and DHT21. It is 3.3V and 5V tolerant and needs only one pin on the Arduino to read the data.
THere are a few libraries out their for the DHT sensors, we are using the Adafruit library.
The bare sensor (what we have here) requires a 10k pullup resistor between VCC and Data (Pins 1 & 2 from the left).
