(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal.

Sealed optical chamber protects sensor from insects and air currents. Temperature compensation for optimum catch performance and false alarm protection. 30 V/m advanced RF protection up to 1 GHz ...

With higher levels of integration to include features such as occupancy detection, health monitoring, and motion and presence ...

this DIY motion trigger for a DSLR is a quick and easy build, and probably loads more fun. The BOM on [Jeremy S Cook]’s build is extremely short – just a PIR sensor and an optoisolator ...

The good news is that Sensify can run on Zigbee networks with a range of chipsets working together, meaning it can be ...

System OverviewThis PIR model is an indoor/outdoor dual detection camera which uses both video and infrared sensor to achieve accurate motion detection functionality. It also supports active ...

As an example, [Circuit Valley] has an IKEA Vallhorn motion sensor for a teardown, it’s as you might expect, a passive infrared sensor (PIR) sensor coupled with a Zigbee interface. Inside the ...

Did you know there are different types of motion detection? There’s computer vision that detects changes at the pixel level; ...
