To build a system where an LED blinks whenever the IR sensor detects an object within its proximity range. This can be used in various applications, such as a simple object detection system or a ...

Light-emitting diodes -- LEDs -- can do way more than illuminate your living room. These light sources are useful microelectronics too. Smartphones, for example, can use an LED proximity sensor to ...

Vishay has introduced a surface mount proximity sensor that can pick up objects 200mm away. Called VCNL30204, the 4.85×2.35×0.83mm devices includes lenses, an IR emitter, PIN photodiode, a 16bit ADC ...

For color sensing in closed environments with no IR light sources, the TCS3x71 Series applications include closed-loop color temperature feedback control in solid-state lighting (SSL) and LED RGB ...

Thanks to the iPhone 4S teardown at iFixit, there may now be an explanation for why Apple restricts the Siri intelligent assistant feature to the iPhone 4S. Apparently, it is indeed a hardware related ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

A non-contact proximity alarm developed by Standex Electronics integrates audio and visual alerts—when a trigger element nears the base element, it illuminates an LED indicator light and sounds and ...

The APDS-9800 integrated ambient light and proximity sensor module comes in a 1.45 x 4.95 x 3.0-mm surface-mountable package that suits cell phones and other handheld portable devices. The unit has an ...

Este projeto utiliza um sensor ultrassônico para medir a distância até um objeto e controla um LED RGB para indicar essa distância com diferentes cores. É uma aplicação prática para demonstrar como ...
