Abstract: Temperature control system and light intensity control system for smart home are becoming more common in these days. The proposed system is to manage the temperature and the light intensity of a given area based on setting by a user of the system with analog temperature sensor (LM 35) and light dependent resistor (LDR). The system contains LM 35, LDR, Ardino Mega 2560 microcontroller and liquid crystal display (LCD). It can support ON/OFF control of the fan system and the lighting system for smart home and its environment.
