The I/O of microprocessor is arranged to export while exports low level, and the low level retention time can not be less than 18ms, so
The I/O of microprocessor is arranged to input state afterwards, and due to pull-up resistor, the I/O of microprocessor is DHT11 DATA line
Uprise therewith, wait DHT11 to make recall signal,
Step 3:
When DHT11 DATA pins detect that external signal has low level, external signal low level is waited to terminate, after delay
DHT11 DATA pins are in output state, export the low level of 80 microseconds as answer signal, and then export 80 microseconds
High level notice peripheral hardware prepares to receive data, and the I/O of microprocessor is now in input state, detects that I/O has low level
After (DHT11 back-signallings), the data receiver after the high level of 80 microseconds is waited.
Step 4:
40 data are exported by DHT11 DATA pins, microprocessor receives 40 data according to the change of I/O level,
Position data " 0 " form be：The low level of 50 microseconds and the high level of 26-28 microseconds, the form of position data " 1 " is 50 microseconds
Low level adds the high level of 70 microseconds.
