Introduction

The inprovement of information and communication
technologies involves their wide usage in remote device
control. Automation system developed in the paper is based
on the use of android application for users’communication
with the web server located in the controlled object. The
server is installed on Raspberry Pi computer, which
contributes to significant reduction of device dimensions.
The control can be performed by using voice commands
from any device that supports download and installation of
Android applications. It involves lighting control,
household appliances control, temperature and humidity Picture 2. The android application's screen shot
control, as well as object surveillance.
The automation of object control is based on web server. It
consists of Raspberry Pi software and application control

Conclusion

The smart house control system is completely developed
and tested in order to show its efficiency. There is a
possibility of its upgrading and further development by
