Introduction

In this project “Visitor Counter With Automatic Lighting“, we’ll combine the functionality of an Arduino microcontroller, a 16*2 LCD display, and an IR sensor to create a visitor counter system with automatic lighting. The system will count the number of visitors passing through a specific area while automatically illuminating the room using LEDs if there is at least 1 person in the room.

Block Diagram

Here’s an explanation of the block diagram for the Visitor Counter with Automatic Lighting system using Arduino, a 16*2 LCD, and an IR sensor:

• The IR sensor detects the presence of visitors passing by.
• Upon detection, the Arduino increments the visitor count and updates the LCD display to reflect the new count.
• Simultaneously, the Arduino triggers the relay module to activate the lighting source providing illumination in the area.
• After a brief delay, the system is ready to detect the next visitor, ensuring accurate counting and efficient lighting control.

Circuit Diagram

Here’s the circuit diagram for your project:

• The IR sensor modules are connected to analog pins A3 and A2 of the Arduino for their data pins.
• The LCD display is connected to the I2C pins of the Arduino (SDA to A4, SCL to A5).
• The LED is connected to digital pin 12 (D12) through a resistor to limit the current.
