Infrared Sensor for Object Detection & Counting

Here is a designed and assembled infrared-based sensor system that detects obstructions by using an IR transmitter (TX) and receiver (RX). When an object blocks the IR beam, the circuit triggers a pulse, activating a buzzer and an LED.

Applications:
-Automated object counting in production lines
-Security and intrusion detection
-Speed measurement in automation systems

This simple yet effective system is built using an LM358 comparator, BC547 transistors, and passive components. The sensitivity is adjustable via a potentiometer, making it adaptable for different environments.
