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
TheDHT22 Sensoris factory calibrated and outputs serial data and hence it is highly easy to set it up. The connection diagram for this sensor is shown below. As you can see the data pin is connected to an I/O pin of the MCU and a 5K pull up resistor is used. This data pin outputs...
