Project Overview This project creates a wildlife camera trigger system that captures photos or videos when animals are detected. A PIR sensor detects animal movement and triggers a camera (GoPro, DSLR, or USB camera) to capture images. It’s perfect for…

Project Overview This project creates an automatic fan control system that turns on a ceiling or desk fan when someone enters a room and turns it off after they leave. It’s perfect for bathrooms, workshops, or any room where you…

Project Overview This project creates a gesture-controlled light switch that turns lights on and off with a simple hand wave. Using a PIR sensor, the system detects motion and toggles a relay that controls the light. A short wave turns…

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’s perfect for monitoring remote locations like workshops, sheds, or entry gates where Wi-Fi may…

Project Overview This project creates a fall detection system that monitors an elderly person’s activity and alerts caregivers when a fall is suspected. Using multiple PIR sensors placed strategically, the system detects unusual patterns—sudden motion followed by prolonged inactivity—and sends…

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…
