Standby Power Control System Based on User's Location for Energy Saving in Smart Home

摘要

This paper designs a system to control the standby power of household appliances used at home. To achieve this, the system detects user's location by sensors in an area which is divided into several sections and controls standby power on or off. The current system controlling standby power is cut off the power automatically if electrical power below a certain amount of power is detected and leads to inconvenience caused by controlling the standby power manually when user is resupplied power from system. Therefore, this paper proposes a standby power control system based on location of user which controls standby power of home appliances in the section to meet both energy saving of electrical power and convenience. For this, the indoor space is separated into a number of zones and the system detects whether user is in the section or not by PIR sensor. To verify the system, we compare power between current system and proposed system through experimental scenario.
