House automotion

Automation systems are being used in all fields that humans are living. In this thesis, Building automation subject is chosen to studied on automation subjects.In designed building automation system, modules which are designed with microcontrollers are used in rooms and a computer software is used for main control panel. The modules which are used in rooms, controls temperature and lightening of room. Lightening knowledge is taken by LDRs (Light Dependent Resistor). Lightening sources are driven by P control algorithm. By gradually lightening source groups, the same light level obtained and get a good return on financial.In modules, TMP35 is used for sensing temperature of room. This temperature knowledge put in fuzzy algorithm in microcontroller software. According to this temperature knowledge fuzzy logic algorithm gives the level of heater or cooler output.By the help of ritz relay, windows position is taken. If a window?s position is change in room which is not activated by user, alarm output of module will be active.On computer software which is written in Delphi, shows temperatures of rooms, temperature wihch is set by user, lightening per cent which is set by user. Besides room temperature according time graph is drawn by software.
