Motion Detector Using PIR and Arduino
The Motion Detector project uses an Arduino Uno, PIR motion sensor, and a 16×2 LCD display to detect human movement and show real-time alerts. It’s a simple and effective system for security or automation applications in homes, offices, or restricted areas.
The PIR sensor detects infrared radiation emitted by warm bodies. When motion is sensed, it sends a signal to the Arduino, which then displays “Motion Detected” on the LCD. When no motion is present, the display shows “No Motion”. A buzzer can also be added to sound an alert when movement occurs.

Motion Detector Using PIR and Arduino
The Motion Detector using PIR and Arduino is a practical and effective security system designed to detect human motion in a specific area. It uses a PIR (Passive Infrared) sensor to sense movement, an Arduino Uno for processing, and a 16×2 LCD (with I2C module) to display motion alerts in real-time. This system can be used in homes, offices, or any space where motion-based automation or monitoring is required.
The PIR sensor works by detecting infrared radiation emitted by warm bodies like humans. When motion is detected, it sends a signal to the Arduino. The Arduino then activates a buzzer (optional) and displays the message “Motion Detected” on the LCD. If no movement is sensed, the LCD displays “No Motion”, keeping the user informed.
This system is low-cost, easy to build, and helps students learn the fundamentals of sensor interfacing, LCD communication, and real-time monitoring with Arduino.
