It was one of my Weekend project as i got a chance to have a hand on the PIR sensor. So, i just got an idea to use this PIR sensor and Piezo electric buzzer to make a alarm by detecting the motion ...

We will showcase two distinct codes for motion detection using a PIR sensor. The first employs a straightforward state-based methodology, efficiently detecting and responding to alterations in the PIR ...

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 ...

Sometimes, projects start in somewhat unlikely places. This one began when [Istvan Raduly] scored a fake raven at a neighbor’s garage sale and decided to turn it into a thunder-and-lightning ...
