PIR & Motion Sensor
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:…
Introduction Traditional pyroelectric materials like lithium tantalate and PZT have served well for decades. However, emerging materials promise higher sensitivity, flexibility, and integration with modern electronics. Graphene-Based Pyroelectric Sensors Graphene has exceptional electronic and thermal properties. Researchers have demonstrated graphene-based…
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…
April 11, 2026 – Northbrook, IL – New Standard for Occupancy Sensors Underwriters Laboratories (UL) has published UL 2680, the first dedicated safety standard for passive infrared occupancy sensors used in life safety applications. The standard addresses reliability, false alarm…
Introduction Healthcare is an emerging frontier for PIR sensor technology. With an aging population and increasing demand for remote monitoring, PIR sensors offer a low-cost, privacy-preserving solution for patient observation. Why PIR for Healthcare? Privacy: No cameras, no identifiable images…
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…
April 10, 2026 – Dallas, TX – Bosch Honored at ISC West Bosch Security Systems received the Security Industry Association’s (SIA) ‘Product of the Year’ award for its BlueLine AI PIR motion sensor at ISC West 2026. The sensor was…
Introduction Agriculture presents unique opportunities for PIR sensors. From protecting crops from wildlife to monitoring livestock health, PIR technology offers low-cost, robust solutions for outdoor environments. Key Agricultural Applications Wildlife Intrusion Detection Deer, wild boar, and other animals can devastate…
Project Overview This project creates a smart night light that turns on when motion is detected and gradually dims over time. The light uses an RGB LED or LED strip and features smooth fade-out effects, making it perfect for bedrooms,…
Introduction With the US Hot Cars Act requiring child presence detection in all new passenger vehicles by the 2028 model year, automotive-grade PIR sensors are becoming a critical component. This article covers the technical requirements and implementation considerations. Regulatory Context…
