PIR & Motion Sensor
PIR & Motion Sensor
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,…
Project Overview This project creates a medicine reminder system that helps elderly or forgetful individuals remember to take their medication. A PIR sensor detects when someone approaches the medicine cabinet, and if it is time for medication, the system plays…
Introduction PIR sensors are inherently sensitive to temperature because they detect thermal radiation. Ambient temperature changes can significantly affect performance, causing false triggers or missed detections. How Temperature Affects PIR Sensors Sensitivity Variation Pyroelectric materials have temperature-dependent properties. Sensitivity typically…
Project Overview This project creates a driveway alert system that detects vehicles or people approaching your property and sends a notification to a receiver inside your home. It is perfect for long driveways, rural properties, or anywhere you want to…
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…
Introduction PIR sensors and modules offer different output interfaces. Choosing the right one and interfacing correctly is essential for reliable operation. Output Interface Types Push-Pull Digital Output Output is actively driven HIGH to VCC and LOW to GND. Can source…
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, perfect for observing…
