Nowdays, an inexpensive hardware (Arduino boards, Raspberry Pi and similar boards, sensors, actuators, etc.) and a huge amount of available information on the Internet gives you a possibility to develop interesting systems with a limited knowledge about electronics, Web and other technologies. These systems are usually part of the global network too which brings us toward Internet of Things (IoT). One of the endless IoT possibilities is definitely home system monitoring. Such systems can provide you the constant information about state of your home (for example insight into past and current values of the physical variables in your home like temperatures and humidity) and consequently advanced control of your everyday life quality (comfort, energy consumption and security).
The article is divided into three parts. The first part gives the information about nodes (software and hardware aspects), the second one deals with the Raspberry Pi setup and in the third one data visualization is presented.
