DHT22 output calibrated digital signal. Small size & low consumption & long transmission distance(20m) enable DHT22 to be suited in all kinds of harsh application occasions. Single-row packaged with four pins, making the connection very convenient.
As you can see, the sensor size is so small when we compared with Malaysia 20 cent. Alternatively the size should be around our index finger size.
Note: Malaysia 20 cent is not included in the packing list. Picture above just for your reference only.
