Project Overview This project creates a wireless motion notification system that uses ESP-NOW protocol to send alerts between ESP32 boards without requiring a Wi-Fi network. It is perfect for monitoring remote locations like workshops, sheds, or entry gates where Wi-Fi…

Project Overview This project creates a touchless automatic trash can lid that opens when you wave your hand or approach with trash. A PIR sensor detects motion, and a servo motor lifts the lid. After a few seconds, the lid…

Project Overview This project creates an energy-saving HVAC control system that automatically adjusts temperature settings based on room occupancy. When a room is occupied, the system maintains normal temperature; when the room is empty for a set period, it enters…

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…

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 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 Create a fun Halloween decoration that comes to life when trick-or-treaters approach. When the PIR sensor detects motion, the ghost lights up with eerie LEDs, plays spooky sounds, and can even move using a servo motor. Difficulty: Beginner…

Project Overview This project creates a smart plant watering system that reminds you to water your plants when motion is detected nearby, or automatically waters based on soil moisture. It is perfect for indoor plants that are easily forgotten. Difficulty:…

Project Overview This project creates a humane dog bark deterrent that uses ultrasonic sound to discourage excessive barking. The system activates only when motion is detected, saving battery life and preventing constant noise. When the sensor detects a dog (or…

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