April 14, 2026 – Boca Raton, FL – ADT Extends Battery Life in New Sensor ADT has announced the ADT Motion Sensor Pro, a new wireless PIR security sensor with an industry-leading 10-year battery life. The sensor uses a CR123A…
Introduction Smart elevators use sensors to optimize operation. PIR sensors can detect if people are waiting or inside, enabling more efficient dispatching. Applications in Elevators Waiting Area Detection Detect people waiting for elevator on each floor. If no one is…
Project Overview Create a fun Halloween decoration that comes to life when trick-or-treaters approach. When the PIR sensor detects motion, the ghost lights up with eerie LEDs, plays spooky sounds, and can even move using a servo motor. Difficulty: Beginner…
April 13, 2026 – Mountain View, CA – Nest Thermostat Gets Smarter Google has released a firmware update for the Nest Learning Thermostat (4th Gen) that improves the device’s PIR presence detection algorithms. The update, version 8.5, reduces false “away”…
Introduction Vending machines are becoming smarter. PIR sensors play a key role in detecting approaching customers, waking up the machine, and powering down when no one is around. Applications in Vending Customer Detection When a person approaches, the machine can:…
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…
