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 ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

In this tutorial, we are going to interface E18-D80NK IR Proximity Sensor with Arduino. The E18-D80NK is an advanced low-cost IR Proximity Sensor with an obstacle detection range of 3 cm to 80 cm.

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 Arduino based IR reflectance sensor can be easily modified and adapted for various practical applications, including line-following robots and proximity or edge detection.
