Description: DHT11 temperature and humidity sensors and communication between the microcontroller 51. According to the communication protocol of the sensor, first by the microcontroller through the I/O port excitation signal generating initiative required, and then passes control to the sensor data line, followed by the while statement microcontroller continuously checks I/O port of the high and low, to achieve the correct understanding of the timing of, parse out the accurate transmission of data
