Light sensors detect the presence or absence of light, and the intensity of that light. These sensors then convert light ...

Engineers are always in search of new electrical project ideas, and finding meaningful projects makes that search worthwhile. Listed below are the latest electrical projects for engineering students.

Abstract This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of ...

To create the project, you'll only need a Raspberry Pi, Raspberry Pi-supported camera, PIR motion sensor, LED, and Arduino. The Arduino monitors the motion sensor and controls the LED, while the ...

CES 2025: Aqara’s Newest ‘Presence Sensor’ Keeps the Lights on Better Than a Motion Detector A presence sensor uses wave radar technology to sweep a room, looking for the slightest movement.

The PIR motion sensor is active and a red LED will light up if motion is detected, plus the display shows a row of rectangles. The latter should show on the first line, so I installed the display ...

The P2 has the same wide-angle PIR sensor and light (lux) sensor as the P1 and can similarly detect motion up to 23 feet away and over 170 degrees horizontally.

Blinding light, guiding light, or something in between, the best outdoor motion sensor lights make sense as a home accessory.

Smart home automation is the ultimate life hack, in my humble opinion. Whether for efficiency, accessibility, nerding out, or just plain laziness, all you need are smart home devices and a little ...
