Shown above is the timing diagram of DHT22. If you compare the timings for ones and zeroes in both
devices you’ll notice that these timings are way different. Same goes for the data, command and
control processes. Here again the datasheet of DHT22 is used to create the library for DHT22 and the
process is just manipulation of a single GPIO pin.
