5. Existing System:-
Manual/Physical gate closing & opening.
Manual switch based gate closing & opening.
Limitations of exiting system:-
Chances of human error.
Time consuming.
A lot of human resource is required.

10. MICROCONTROLLER
It has a 40 pins
4096 bytes on chip program memory
128 bytes on chip data ram memory
32 bidirectional i/o lines
16 bit timers/counters
64 kilobytes external memory addressability
High speed programmable serial port
128 user defined flags
11. POWER SUPPLY:
12V Power Supply is Required
8051 operates on dc power supply of +5v
+5v is connected to vcc(40pin)&vss(20pin)
It’s operating frequency is 12MHZ
IR SENSOR:
