The only real downside of this DHT\u00a0 22 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.<\/strong><\/p>\n<p><em>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.
