    This thesis describes the automation of turning lights on and off in the room and temperature measurement outside and inside the room. Light in the room is controlled by brightness and the presence of people in the room. Operation of the system can be checked and adjusted via the internet. The development board Arduino Uno with added module Arduino Ethernet Shield was used. Movement is detected by a passive infrared sensor. Departure from the room is detected as interruption of signal from the infrared light emitting diode. The temperature is measured with a negative temperature coefficient thermistor connected to the analog input. The system is connected to the computer through a network connection. Computer collects and stores data. From the shared data the web application shows graphs of temperature, brightness and light use. On the website the highest, lowest and average temperature for a selected period can be observed. It is possible to monitor the entry and movement in the room. By turning off the lights when the room is not used, electricity is saved. This system can monitor temperature and thus heating. This way the energy consumption can be analyzed. When using only one room the savings due to this are small. If the system is extended to the entire house, the savings can be greater. Other types of sensors can be connected to the controller.
