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) ...

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 ...

Motion detection is the magic ingredient in the current wave of do-it-yourself home security cameras. Thanks to built-in sensors that vigilantly monitor their field of view for movement, you can go ...

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

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 ...

The Multi-State Sensor (P100) first launched at CES ...

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 ...
