6x DHT22 - Temperature and Humidity Sensor

The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old. Simply connect the first pin on the left to 3-5V power, the second pin to your data input pin and the right most pin to ground. Low cost 3 to 5V power and I/O 2.5mA max current use during conversion (while requesting data) Good for 0-100% humidity readings with 2-5% accuracy Good for -40 to 80°C temperature readings ±0.5°C accuracy No more than 0.5 Hz sampling rate (once every 2 seconds) Body size 27mm x 59mm x 13.5mm (1.05" x 2.32" x 0.53") 4 pins, 0.1" spacing
