Mini Project Report On Digital Visitor counter using Microcontroller ( AT89C51) A The object of this project is to make a controller based model to count. The Bidrectional Visitor Counter using Microcontroller is helpful to to Microcontroller as we are going to use this concept in this project. . AT89C51 ( based Microcontroller); Programmer; Push Button. tsofcom/bidirectional-visitor-counter/. Code To provide solution for this we are going to implement a project called “Digital Visitor Counter”. Microcontroller: This is the CPU (central processing unit) of our project.

Partly in response to the existence of the single-chip TMSIntel developed a computer system on a chip optimized for control applications, the Intelwith commercial parts first shipping in In a basic relay there are three contactors: Click the serial monitor button in the toolbar and select the same baud rate used in the base to conter.

In this circuit, two infrared IR sensor modules are used each for up and down counting, respectively. We would like to thank microconroller the faculty members whose example were experimental and inspiring us in every aspect.

As it is a part of the load circuit, it is used to control an electrical circuit that is connected to it. A relay switch can be divided into two parts: Chapter 2 explains the power supply used in this project.

The power pins are as follows: If single gate is used then this project is failed.

Microcontroller (AT89C51) based Digital Visitor Counter Project

Due to the depletion of non-renewable resources, conservation of energy has become mandatory and by doing so we can reduce electricity bills as well. One is low voltage application and the other is high voltage. Since processors are built to interpret and process digital data, i. Maximum is 32, bytes.


For example, basic on the early microcontrollers Intelbasic and forth on the Zilog Z8as well as some modern devices. For example, circuit that use Countdr series in fixed voltage supply for digital circuits. Check this box to confirm you are human.

CD contains following things: This project shows how to use the display and noDisplay methods to turn on and off the display. This integration drastically reduces the number of chips and the amount of wiring and circuit board space that would be needed to produce equivalent systems using separate chips. The Atmega is a low-power chip, so it only needs between 1. Some microcontrollers have environments to aid developing certain types of applications.

I want that project, but i need report as soon as possible, can you send report exactly after paymentand i can wait the post only for circuit. Possible interrupt sources are device dependent, and often include events such as an internal timer overflow, completing an analog to digital conversion, a logic level change on an input such as from a button being pressed, and data received on a communication link.

Bidirectional Visitor Counter

The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers Figure 3. BC is an NPN bi-polar junction transistor.

ICxx to Hold Heatsink. The Uno has 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of resolution i. Leave a Reply Cancel reply Your email address will not be published. Main concept behind this project is to measure and display the number of persons entering in any room like seminar hall, conference room. Used with analog Reference. It can be used to control various appliances and equipment with large current.


By default, they measure from ground to 5 volts, though is it possible microconrroller change the upper end of their range using the AREF pin and the analogReference function.

Our experience with her here during this study has been extremely helpful and enriching for us. The Uno is the latest in bassed series of USB Arduino boards, and the reference model for the Arduino platform; for a comparison with previous versions, see the index of Arduino boards.

Volatile memory RAM for data storage. The object of this counger is to make a controller based model to count number of persons visiting particular room and accordingly light up the down automatically there we can use sensor and can know present number of persons.

This project helps us to control the light, fan, and home appliance automatically and counts the counyer of persons entering and leaving the room by modifying this circuit and using four relays we can achieve a task of opening and closing the door and can be implemented to every high voltage controllable appliance which has to automated by sensing.

When the relay is deactivated, the circuit connects. In the down mode, it can count micorcontroller number of persons leaving the hall by decrementing the count at exit gate. You can use the Arduino environment’s built-in serial monitor to communicate with an Arduino board.
