PIR & Motion Sensor
Introduction With the explosion of smart home devices, choosing the right PIR motion sensor can be overwhelming. This guide walks you through the key considerations to find the perfect sensor for your specific needs, whether you’re building a new system…
Project Overview This project connects a PIR sensor to IFTTT (If This Then That), allowing you to trigger thousands of smart home actions. When motion is detected, you can turn on lights, send notifications, log data to spreadsheets, control smart…
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…
