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 ...

The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

This project unveils a compact and efficient fire alarm system, thoughtfully crafted using the versatile Arduino Uno microcontroller 🤖 and an IR (Infrared) sensor 🌟. Designed with safety in mind 🛡️ ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

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 ...

If you are interested in creating a low-cost contactless infrared thermometer powered by the Arduino platform, you may be interested in a new project published on the Instructables website and ...
