This paper focuses on the home temperature control system which can maintain the temperature at certain level. The home temperature controller is commonly used in all area of the world as the human thermal comfort becomes necessary. It can also reduce unfavourable condition in the home due to the unpredictable weather. The proposed system is not only the automatic home temperature sensing and control system but also the PIC microcontroller based controller. This control circuit is functioning without needed support from the human to control all the process. There are several temperature sensing techniques in widespread usage. Among these, the temperature sensor LM35DZ is used in this home temperature control system. In this control system, the temperature of the home is kept within 20°C and 28°C. By sensing the temperature inside the home, high temperature conditions and very low temperature conditions can be detected and actions can be taken to keep the temperature of a home within the desired temperature ranges. The microcontroller drives the heating and cooling elements to adjust the temperature. The LCD display is also provided to know the temperature status of the home easily.
