Project Overview This project creates a self-powered PIR motion sensor that runs entirely on solar energy. It’s ideal for remote locations where running power cables or changing batteries is impractical. The system stores energy in a supercapacitor or rechargeable battery,…

Project Overview This project creates a smart night light that turns on when motion is detected and gradually dims over time. The light uses an RGB LED or LED strip and features smooth fade-out effects, making it perfect for bedrooms,…

Project Overview This project creates an occupancy counter that tracks how many people are in a room. Using two PIR sensors placed at a doorway, the system detects direction of movement (entry vs. exit) and maintains a count of current…

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.…

Project Overview This project creates a hands-free garage door opener that detects when your car approaches and automatically opens the door. Using a PIR sensor mounted near the driveway, the system detects your vehicle’s heat signature and triggers a relay…

Project Overview This project creates a smart baby monitor that detects when your baby wakes up and sends an alert to your phone. Unlike traditional audio or video monitors, this system uses a PIR sensor to detect movement in the…

Project Overview This project converts a standard sink faucet into a touchless automatic faucet. When you place your hands under the faucet, a PIR sensor detects motion and opens a solenoid valve, allowing water to flow. When you remove your…
