The traditional home appliances outlet can be transformed into a prototype of Bluetooth Smart outlet by conjunction with a Bluetooth Smart sensor tag. With Bluetooth received signal strength indicator; RSSI, to determine the receiving tag is within range of the signal coverage and the method proposed in this thesis can let the Bluetooth Smart Sensor tag has the automatic mechanism to turn on or turn off the external circuit in the outlet.
During the concept validation phase, a Bluetooth low energy RSSI measurement application equipped smart phone is used to measure and collect signal strength and distance data of the testing Bluetooth devices. Such data are statistically analyzed and compared with research data from past studies. It is found that the Bluetooth Low En-ergy technology application is most ideal within 3-meter distance in indoor scenario, with applicable distance no more than 10 meters.
In the prototype development and testing phase, two Bluetooth Smart sensor tags are used as transmitter and receiver respectively, and one of the General Purpose Input Output (GPIO) pin on the receiver is integrated with a power socket to form a Bluetooth Smart outlet prototype. The Bluetooth transmitter and receiver are manually paired to simplify the development process during this prototyping phase. The Bluetooth Smart outlet prototype developed in this study will help improve standby power consumption of traditional appliances by turning the power off completely when user is not within the proximity.
