Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

Module provides integration and flexibility for passive infrared (PIR)-based motion detection applications including customer sensing, lighting control and other energy management purposes. The ...

A new motion sensor incorporates micromachined thermal transistors to facilitate human presence and motion detection in security systems, home automation equipment, and Internet of Things (IoT) ...

Many close-proximity motion detectors use the classic, widely available passive-infrared (PIR) approach, which is effective but has limited sensitivity and adjustability, and can’t “see” through ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

DMP is pleased to introduce the 1122 Wireless PIR (Passive Infrared) Motion Detector. Available now for order, the 1122 comes in a sleek tear-drop shape that has all of the functionality of the 1121 ...

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...

SwitchBot has announced a new product called the Presence Sensor with mmWave Radar. This sensor is built to detect people in ...

We’re still not sure exactly how [connornishijima]’s motion detector works, though many readers offered plausible explanations in the comments the last time we covered it. It works well enough, though ...

OPTEX, Inc. is pleased to announce the new family of wireless battery-operated indoor PIR detectors for direct panel integration: the WFX-360 and WNX-40 series. The WFX-360 series is a 360° wireless ...
