Start transmit 1bit data Start transmit next bit data
26-28us voltage-length means data "0"
Host signal Sesnor's signal
Single-bus signal
------------------------------------------------------------------------------------------------------------------------------------
Step 3: AM2303 send data to MCU
When AM2303 is sending data to MCU, every bit's transmission begin with low-voltage-level that last 50us,
the following high-voltage-level signal's length decide the bit is "1" or "0".
Check bellow picture for step 3:
