PIR & Motion Sensor
PIR & Motion Sensor
Project Overview This project creates a basic home security system that sends SMS alerts to your phone when motion is detected. The system uses an Arduino Uno, a PIR sensor, and a SIM800L GSM module. It’s ideal for monitoring remote…
Project Overview This project creates a smart mailbox notifier that alerts you when mail is delivered. A PIR sensor detects motion inside the mailbox when the mail carrier opens the door or inserts mail. An ESP32 sends a notification to…
Project Overview This project creates an automatic pet feeder that dispenses food when your pet approaches the feeding station. The system uses a PIR sensor to detect your pet’s presence and a servo motor to open a food hopper. You…
Project Overview This project creates an automatic staircase lighting system that turns on LED strip lights when someone approaches the stairs and turns them off after a set delay. Perfect for improving safety on stairs at night while saving energy.…
