Recent advances made in the automotive world have found an unlikely application: a new high-performance portable lantern. And it’s such a cool bit of kit that it could change the way we light the ...

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 ...

Scientists used tiny new sensors to follow the insects on journeys that take thousands of miles to their winter colonies in Mexico. Scientists used tiny new sensors to follow the insects on journeys ...

Paul and David Bradt’s Ardiono Projects offers multiple ways to use Arduino and Raspberry Pi microcontrollers for your model railroading projects. Buy the book here. Code for Button/Blink Test (SN095) ...

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) ...

Murata SMD TYPE IRS-D200ST00R1 is one of the world’s smallest PIR motion sensors at just 6 x 6 mm in size and with a 2.6 mm thickness. Its name implies, it’s a reflowable SMD component, which ...

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.

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) ...
