Model No. 145:- The main motto of the project is to utilization of sensor with combination of embedded equipment for the door opening systems. This project describes the design and implementations of automatic controller for the door. The door opens when any human movement is detected near the door it detects with help of a PIR (Passive infrared) sensor detects the movement and sends a signal to the transistor, in turn gives interrupt signal to a programmable microcontroller of 8051 family, the output signal form the microcontroller is fed to the DC motor which is used to open the door and close the door which is driven by a motor driver IC. Interrupt signals can be used to stop power to the motor in the event of locked rotor condition. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.
