IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

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 ...

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 ...

Oil and gas production and work in confined spaces exposes field personnel to a variety of toxic and explosive gases in everyday drilling, processing, transport, and municipal operations. Explosive ...

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

Active IR sensors include a light source, often a laser or LED, which emits IR radiation and detects the reflected rays from nearby objects. On the other hand, passive IR sensors (PIR) detect the ...

This project utilizes an Intel Galileo microcontroller connected to multiple LEDs, IR sensors, and an LDR (Light Dependent Resistor) module to create a smart lighting system. The system is designed ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...
