PIR & Motion Sensor
PIR & Motion Sensor
Introduction Smart classrooms use technology to enhance learning and save energy. PIR sensors contribute to both goals through occupancy detection and automated control. Applications in Classrooms Occupancy-Based Lighting and HVAC Lights and HVAC automatically turn off when classroom is empty,…
Introduction Wireless PIR sensors are essential for modern security systems, offering easy installation without wiring. This guide covers the best options for 2026, focusing on range, battery life, tamper protection, and compatibility. Key Features for Security Sensors 1. Tamper Protection…
Project Overview This project creates a smart mirror that displays information (time, weather, calendar) when someone approaches, and turns off the display when no one is present. The PIR sensor detects motion and triggers the display via Raspberry Pi. The…
Project Overview This project creates solar-powered pathway lights that automatically turn on when someone walks by. The system uses a PIR sensor to detect motion and turns on LED strips for a set duration. Solar charging keeps the battery topped…
Project Overview This project creates a smart feeding reminder for your aquarium. When you approach the fish tank, the system checks if it is time to feed and plays a voice reminder if needed. It also tracks the last feeding…
Project Overview This project creates a low-power security system specifically designed for RVs, motorhomes, and campers. When motion is detected inside or around your vehicle, the system sends an SMS alert to your phone and can trigger an alarm. The…
Project Overview This project creates a smart laundry reminder system that detects when you enter the laundry room and reminds you if there is a load waiting to be transferred from washer to dryer or from dryer to basket. It…
Project Overview This project creates a simple but effective security system for your shed, garage, or workshop. When motion is detected, the system sends an email alert to your phone or computer. It can also trigger a siren or flash…
Introduction Pyroelectric sensors are widely used in flame detectors for industrial safety systems. Unlike motion detection, flame detection relies on sensing the characteristic flicker of flames and their spectral signature. Flame Characteristics Flames from hydrocarbon fires have two key properties…
Project Overview This project creates an automatic dust collection system for your workshop. When you approach a power tool (table saw, miter saw, router table), a PIR sensor detects your presence and turns on the dust collector. After you leave,…
