In our everyday lives, environmental conditions like temperature and humidity can have a big impact, whether it’s in your home, office, greenhouse, or server room. Imagine leaving your room for a few ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Panasonic Industry unveils a new generation of passive infrared (PIR) motion sensing arriving with a clear message: performance no longer needs to come at the cost of design. A recently introduced ...

Panasonic Industry has launched its latest innovation in PIR motion sensors: the Flat Wide Detection Type (12 lens), being the first product incorporating the new PaPIRs+ technology. Engineered for ...

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 ...

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) ...

Abstract: Pyroelectric infrared sensors (PIR) are excellent devices to detect human/animal presence with a small form factor and rugged design, for cost-effective surveillance. They are widely used to ...

ABSTRACT: This study investigates the optimization of Fresnel lens designs using Zemax software, with a focus on minimizing beam divergence by controlling the output spot diameter on the image plane.

Motion sensors are a type of technology that are used in a wide variety of applications, from home security systems to automatic doors in public places. They are designed to detect movement and ...

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 ...
