Abstract

In this demonstration, we propose a line of sight LED-to-camera communication system based on an ordinary LED and a smartphone. We designed a cheap temperature sensor prototype as a proof of concept of a near communication framework for the Internet of Things. To illustrate a typical use case, we have programmed the micro-controller to broadcast the ambient temperature value through the LED. The user, with his smartphone and our Android application can then retrieve the transmitted information, aiming the board with the camera.
