Data acquisition part running on an Arduino Nano. It controls the infrared light barrier, detects trigger levels and communicates with a master computer over USB serial. Data recording part running on ...

This project is an object/person detection counter built with an Arduino Uno, an IR sensor, and a 16x2 LCD display. Whenever an object (e.g., a person walking past or a hand wave) interrupts the IR ...

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 ...

In the realm of DIY electronics, the Arduino UNO has emerged as a versatile platform for a myriad of projects. One such innovative project is the creation of a low-cost thermal camera, as demonstrated ...

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 PIR motion sensor consists of 3 pins-VCC, GND, and the Data Output Pin. VCC is the power pin of the module. Out is the data Output pin of the module.it goes high when motion is detected. GND is ...
