Abstract: Pyroelectric infrared (PIR) sensors are much promising for device-free localization (DFL) due to their advantages of lower cost, low power consumption, and privacy protection. Most PIR-based ...

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 document my learning in order to be able to inspire other people to make ...

Every smart home owner is likely to be familiar with “passive infra red” (PIR) motion sensors as they’re an easy way to start off making a home a little smarter They’re quite distinctive too, with the ...

The PIR library implements a class to monitor 1 or more PIR sensors. The library supports default 8 PIR sensors per object, which typically are added in setup(). It is possible to add a sensor (pin) ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

An optical drone, dipping low before a herd of antelope, collects footage for a new documentary. Equipped with advanced optics fixed securely to its unobtrusive body, it can take high-quality imagery ...

Abstract: In India, nearly 20 percent of the electricity is lost due to technical and commercial reasons. Three billion units of power are wasted every year. The Automation of lighting system with the ...
