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 ...

Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino and an LED, it can create ...

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 ...

Old infrared remote controls can be a great way to interface with your projects. One of [AnalysIR’s] latest blog posts goes over the simplest way to create an Arduino based IR receiver, making it ...

Intrusion Detection Systems (IDS) strive to catch computer system intrusion & utilize by any garnering and analyzing data. Wireless IDSs garner all local wireless transmissions and generate alerts ...

It is critically important for instrument users to understand what the sensors in their instrument cannot properly measure, as well as what they can. Non-dispersive infrared (NDIR) sensors are ...
