Arduino temperature monitoring solution for routers

Abstract

An important element in communications systems is the router. The paper proposes a remote temperature monitoring system for it. This was implemented based on Arduino Uno development platform. In addition, an Android user-friendly interface has been created; it can be installed on a smart terminal (phone or tablet) and its role is to display the router temperature and to notify the user if it has exceeded a maximum set value. There are two methods of notifications: one is using different colors for the displayed temperatures and the other using an alert. The temperature is measured with a sensor and the data is then processed by the microcontroller and sent to the Bluetooth module using serial interface. Also, the measured values can be seen on an LCD display. The hardware, software designs and the simulation and experimental results of the proposed system are presented.
