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 ...

# Ultrasonic and Infrared Sensor with Arduino Uno ## Overview This project demonstrates how to use both an ultrasonic sensor and an infrared (IR) sensor with an Arduino Uno. The ultrasonic sensor is ...

This project involves designing and constructing a digital tachometer using an Arduino Nano. The tachometer measures the rotational speed of a motor or any rotating object and displays the RPM ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

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 ...

[Fernando] sent in a tip about a pet project he’s been working on. It’s an interesting take on a 3D scanner. He used a stepper motor to rotate the object being scanned, and an Arduino for control, but ...

Abstract: The oil detection buoy is based from the previous study of researchers which used a non-contact infrared sensor oil detection buoy. The researchers engaged minimal changes with the design of ...
