I just picture on the 8051 chip, the infrared sensor automatic door map, so I am in the extra points
The following answer to the uncle to find to find you why ..... hope to help me to design or find a can
8051 chip is what stuff? Automatic door should be what brand + what model.
This is very simple With an infrared sensor, after induction, the microcontroller detects the signal after closing the external relay, the relay link is to push the door of the DC motor. After running for a while, turn off the relay.
