DHT22 Digital Humidity And Temperature Sensor Connecting Cable
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).
It's 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 rightmost pin to ground.
Although it uses a single-wire to send data it is not Dallas One Wire compatible!
If you want multiple sensors, each one must have its own data pin.
