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 ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

Speed-Accel-Meter is a user-friendly application that allows you to measure the speed and acceleration of moving objects. It uses an Arduino board, three infrared (IR) sensors, and a 16x2 LCD screen ...

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 ...

This project uses an Arduino UNO and IR sensors to create an intelligent traffic light system that adapts signal timing based on real-time vehicle presence.

An Infrared Distance Sensor as well as Processing is used by Arduino in order to visualize real world sensor data measurements. An Infrared Distance Sensor as well as Processing is used by Arduino in ...

Abstract: This study presents a real-time IR distance sensing system for cyber-physical systems (CPS) applications, integrating Arduino hardware control with LabVIEW analytics. The system employs an ...

[Brian] started out with a clear and concise goal, “allow a regular human to associate an audible tone with a temperature from an infrared contactless thermometer.” With his latest project, the ESPeri ...
