The robot uses a whopping 32 IR sensors to follow a black line across a concrete workshop floor, adjusting its path using a steering motor salvaged from a power wheelchair. An Arduino Mega Pro ...

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 ...

Sometimes it’s nice to have a widget to do a single task and avoid getting distracted by the supposed simplicity of doing it with an app on a smartphone. [Dina Amin] built a timer from an old ...

Labeling bottles manually takes a good chunk of time and effort. Addressing this, the YouTube channel Easy Home Made Projects has developed a DIY automatic labeling machine using an Arduino Nano, a ...

Learn how to interface a flame sensor with Arduino to build a simple fire alarm system that detects fire using infrared light and activates an alert through a buzzer and LED. How Does MQ-2 Flammable ...

In a nutshell, it is a proximity-based wireless communication standard. Unlike Wi-Fi or Bluetooth, however, NFC interaction is limited to an extremely short range. Besides smartphones, you can ...

Abstract: Context-centric sensor-based proximity detection (or, contextual co-presence detection) is a promising approach to defend against relay attacks in many mobile authentication systems, ...

This is an Arduino library for SDI-12 communication with a wide variety of environmental sensors. It provides a general software solution, without requiring any additional hardware, to implement the ...

In this paper, we systematically investigate Machine Learning (ML) methods to detect proximity by analyzing publicly available dataset gathered from smartphones’ built-in Bluetooth, accelerometer, and ...
