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 ...
IoT-based farm security and monitoring system using Arduino, GSM, and IR sensors. This project implements a geofencing system for agriculture that detects intrusions (humans, animals, or unauthorized ...
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 ...
This project is a simple and effective Fire Detection System built using an *IR sensor, **Arduino UNO, **16x2 LCD display, and a *buzzer. It continuously monitors infrared radiation and alerts the ...
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 ...
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 ...
