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 ...

Sensor‑based currency counter using an IR sensor and a colour sensor with an Arduino and 16x2 LCD. Notes are detected as they pass, their denomination is identified from colour patterns, and 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 ...

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 ...

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 ...

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 ...
