The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

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 ...

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 ...

As a biomedical equipment technician [Adam Outler] equipment needs to be in top working condition. The emergency room staff were complaining about erroneous noise on the electrocardiogram and it’s his ...

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 ...

Parking sensors have become a must-have these days given the crowded cities we live in, but instead of paying hundreds of dollars to get them installed in your car, why not build your own at home?

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 ...

Abstract: A remote radiation monitoring system is proposed. A method for measuring and analyzing the background radiation level in a given space is developed, based on a Geiger-Müller sensor. The ...

[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

Will not be affected by the type of liquid. Can detect the liquid level of boiling water Strong compatibility penetrates all kinds of non-metallic containers or pipes such as plastic, glass, ceramic, ...
