The temperature and humidity sensor is also named DHT21, compared to the DHT11, this sensor is more accurate and more safety for it was covered with a plastic shell. The sensor measures humidity of the surrounding air by the capacitance and measures the temperature based on the use of a NTC. Compared to the am2301, the am2320 is advantaged in the volume and the communication mode, am2320 is so tiny and just as big as the thumb’s nail, it has two types of the communication mode: unibus and I2C.
