An object counter using an IR sensor and Arduino

An object counter using an IR sensor and Arduino

In this article we will resume the topic started with in “Detecting obstacle with IR Sensor and Arduino”. More in details, we are going to use the IR sensor like an objects counter.

The counter application is often used for:

counting people traversing a certain passage or entrance. For example, in commercial buildings there are gates which control user access or presence often used to optimize energy consumption; counting objects or merchandise in industrial sector; etc.

A counter can be made not only with IR technology but also with thermal imaging systems that use an continue reading...

Detecting obstacle with IR Sensor and Arduino

An object can be detected with an infrared system consisting of an infrared transmitter and a receiver. More in detail an IR transmitter, also known as IR LED, sends an infrared signal with a certain frequency compatible with an IR receiver which has the task to detect it. There are different kind of IR sensors for different type of application. IR technology is used, for example, in proximity sensors to detect a near object, in contrast sensors to find a path or in counting sensors to count continue reading...
