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;
A counter can be made not only with IR technology but also with thermal imaging systems that use an array of sensors which detect heat sources or using machine vision which usually requires complex image processing algorithms. continue reading…
