3.3. Lift and motor section
In lift section, there is a light beam and LDR to know whether a car has entered the lift or not. When the GREEN LED of indicator section glows, that means the lift is ready for the car to enter. When the car enters the lift, the light beam falls on LDR present in the lift gets cut and it gives a signal that a car has entered the lift. Then program decides which floor lift has to go and gives a signal to motor section. Circuit diagram of sensor present in lift is shown bellow.
The motor section is a mechanical part of the model which is used for taking the lift up/down. When the lift has to go up, program gives the signal and the motor rotates clockwise and if it has to go down, it rotates anticlockwise. First 4 pins port A is connected to motor. Power transistors must be connected to drive the motor. Circuit diagram of this section is shown bellow.
3.4. Sensor section
Sensor section contains LDR’s .These LDR’s are connected to each floar to give information if any car has to come down. When a person needs to come down from a particular floor to ground floor, he is expected to focus the headlight the car onto the LDR placed in that floor. When light falls on LDR its resistance decreases. Hence IC 555 triggers and gives a signal. Program identifies that signal and gives a signal to motor section. The circuit diagram sensor is shown bellow. In this project same circuits is connected to three floors. This circuit is different if you compared with that of lift sensor shown above.
3.5. LCD Section:
In this project LCD is used to display some messages which is useful to car owners. Here 2X16 LCD ( Liquid Crystal Display) is used. This is used to display messages like
WELCOME TO CAR PARKING SYSTEM
LIFT IS BUSY PLEASE WAIT
PLEASE ENTER YOUR PASSWORD
Circuit diagram of LCD section is shown bellow. LCD is interfaced with 8051 microcontroller.

sir
i am doing this project .can you mail the pcb layout of this project with all inter connection and its complete circuit diagram.
sir,it will help me more,plz mail me as soon as possible.
sory sir, my email id is ajaykumar110126@gmail.com
Im interested in this project could u plizzz send me the full schematic,circuit diagram and coding or flow chart plizzzzz its urgent
can you plz mail me the details of this project with circuit diagram…i want to make this on as my major project,plz mail me as soon as possible
sir,can u plz send me project report along with ppt of this project
sir can you please send me the circuit diagram of this project. it will be very helpful for us.
thank u in advance…..
Sir, Im interested in this project could u plz mail me the complete circuit diagram of the project?
Plz send me full circuit diagram plz I do this project in final year. Plz help me sir. & all students
Sir, I am a B.E. student and I want to do this project as my final yr project. So i want the complete ckt diagram of this project. I request you to please send me at my email address as early as possible.
Dear sir ,
i’m very interested on this project , can you send me the full details of this nice project ?
Very appreciate 🙂
dear sir, I am also intersted in doing this project, bt i hv ltl confusion, that when a car comes near to ground floor then wheather the user is inside or not, also if at any floor there are 2 cars alerady parked and next car has to be park then how the car will go from lift to that perticular space. Again if when any user wants to go and needs his car back then how his car will get back to perticular person. According to this project it is applicable only for the single car.
sir i m doing this project….need your assistance..contact plz
SIR,
I am the student of B E final yr , in intrested your project . but i have some problem in this project, so please send me circute dig and flow chart, coding please sir its urgant, please send as soon as possible.
Thanks a lot.
I am sty diploma final year sir this project all detills hear. but circuit diagram not pll help me…… pll Response me
sir , i m final year student and i want to make multilevel car parking system as my minor project but i have some difficulty in programing pllzz help me..
plz send me the complete source code in hex file and assembly of this project…………
How we know that parking space is available or not I.e if in each floor their is capacity of park 10 car then how we know that 10 cars are parked or not??
