What are the features of this project?
This project has many features, such as:
- It can count both the entering and exiting visitors of the place.
- It can also count the total number of visitors currently present in the place.
- It can display the count value up to 9999.
- It can reset the count value to zero if it exceeds 9999 or by pressing a button.
- It can operate in both up and down modes depending on the input from the sensors.
- It can display the count value on four seven-segment displays using multiplexing technique.
How does this project work?
This project works on the principle of infrared sensing and microcontroller programming. The project consists of three main parts: the microcontroller, the seven-segment displays, and the infrared sensors. The microcontroller is the brain of the project that controls all the functions. The seven-segment displays are used to show the count value. The infrared sensors are used to detect the presence of an obstacle and send a signal to the microcontroller.
The microcontroller is connected to a crystal oscillator and a power supply. The data pins of each seven-segment display are connected to port P2 of the microcontroller. The first four pins of port P1 (P1^0-P1^3) are connected to the base of four transistors through four 330 Ω resistors. The collector of each transistor is connected to the common cathode of each seven-segment display. The emitter of each transistor is grounded. The transistors act as switches that enable or disable a particular seven-segment display depending on the signal from the microcontroller. The fifth and sixth pins of port P1 (P1^5 and P1^6) are configured as input pins that receive signals from the infrared sensors. The infrared sensors are placed at the entrance and exit gates of the room or hall. Each sensor consists of an IR transmitter and an IR receiver. The transmitter emits infrared rays and the receiver detects them. When an obstacle comes in between the transmitter and receiver, the rays are interrupted and the receiver sends a high signal to the microcontroller. Depending on which sensor is triggered, the microcontroller either increments or decrements the count value and displays it on the seven-segment displays.
