VISITOR COUNTER WITH AUTOMATIC LIGHTING

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.

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.

PCBWAY is known for producing PCBs of exceptional quality and maintaining high standards, which is why many people trust them for their PCB and PCBA

Below are some of my PCB’S manufactured by PCBWAY and I am fully satisfied by their Quality of service they provide

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.
