Introduction
A home with lights accidentally left on not only has financial consequences but environmental consequences as well. Kuleana is the Hawaiʻian value that translates loosely to responsibility and the responsibility to not overuse or underuse resources. Home appliances such as lights and fans are frequently used but can also be forgotten resulting in them being left on consuming electricity. The purpose of this project is to research household energy consumption and to design a motion sensor to automatically turn lights that are left on off when triggered. According to a study by the Natural Resources Defense Council 1., electricity consumption contributes to nearly 1 billion tons of carbon dioxide pollution. The CO2 emissions not only contributes to global warming, but leaving home appliances operating has financial repercussions too. Inactive devices on ‘standby’ mode adds up to approximately $19 billion annually. Having kuleana means to reduce energy usage and not wasting resources.
Conclusion
The purpose of this project was to reduce electricity usage by building a motion sensor to turn off lights when passing it. The project was accomplished within the six-week time frame. Starting off small, a motion sensor was programmed to turn off a single LED light. When there was motion, the LED would turn on. A power outlet with a relay was built next. By building the power outlet (Fig.7), lights can be plugged in and programmed to turn on or off. Adding the motion sensor to the power outlet allows the lights to operate with the sensor. A lamp was plugged in to the outlet and when motion was detected the lamp would turn off (Fig. 8). In order to add to this project, future ideas include connecting more household appliances to the motion sensor, improving the motion sensor to turn off all appliances left on when triggered and/or learning to connect mobile devices to power outlets to automatically turn off appliances when leaving a specific location. Calculating the amount of energy used before the motion sensor and the amount saved after using it can give better understanding of the effects of energy consumption.
Method
The first step of the project was the integration of the motion sensor with the Arduino. After setting up the motion sensor Arduino,and a light-emitting diode (LED) was attached (Fig.1). The LED was programmed to turn on when motion was detected and to turn off when there was no motion (Fig. 2). The next step was building a standard three prong power outlet while incorporating the relay as a switch for it (Fig. 3). The purpose of building the power outlet was to provide the option for different appliances to be plugged in and operate with the Arduino. Stripped wires were connected to the relay and power outlet (Fig. 4). A power surge was cut and the hot, neutral and ground wires were taken out and stripped. The hot wire from the power cord was connected to the relay and the neutral and ground wires were attached to the outlet (Fig. 5).The power outlet was built once all the wires were successfully connected. Using the breadboard, the motion sensor and the assembled power outlet were connected together (Fig. 6). The relay was then programmed to turn the outlet on when the motion sensor was triggered. When motion was detected, the relay would switch the power outlet to work according to the program commands.
Results
The motion sensor was integrated with a power outlet. The power outlet switched on with the relay when the motion sensor was triggered. A lamp was plugged into the power socket and turned off with motion.
