This project proposes the energy management for smart environment. The overall control scheme is mainly governed by an embedded microcontroller. Economic crisis and the risen energy price have forced every country to reduce their energy usage and try to be economical on energy consumption. In this project IR sensors are used to find out the intruder enters the home and the devices are controlled using zigbee (wireless transmission). The system will count the number of human presence in the room or hall. This process is useful to save the electrical power and the system will turn on/off every plugged electrical appliances including light bulbs, fans, TV, etc. LDR senses higher light intensity at day time so that the relay will turn off the light bulbs, the devices will be automatically turned on at night times, and this will typically save the electricity. The temperature sensor used to sense the temperature range of the home, if it exceeds the threshold temperature fan will be automatically turned ON using relay, when temperature reaches normal condition relay will turn OFF the fan. The whole process is based on the human count inside the particular room/hall. Thus based on the human count, every devices inside the room/hall is controlled using sensors and zigbee technology.
