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). AM2302 Sensing Module is 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
