Motion Activated, Temperature Controlled (Matc) Electric Fan

Abstract

The major objective of the study was to design and develop a motion activated and temperature-controlled electric fan. It is the most practical and affordable way of keeping areas cool especially during hot and humid months. In the Bulacan State University, many electric fans installed in lecture rooms are left unattended even after class hours. This translates to unnecessary fire risks and/or excessive electric consumption of the University. It is in this light that the researchers developed a device that presents an opportunity for the development of intelligent appliances that can save on electricity consumption due to its innovative and eco-friendly features. Various designs were put forward and a careful consideration of each plan was done, with special considerations to the need for innovative appliances that can be very useful in terms of energy efficiency and environmentfriendliness through an integrated multi-dimensional sensor system. The study utilized the developmental research method in the fabrication of the project. The focus on the procedures and processes involved analysis, development and evaluation of the project and in validating the project. The steps involved in this method include the following: (1) studying research findings pertinent to the project; (2) developing the project based on the findings; (3) field testing of the project, and (4) revising the project. The project was developed in sixty (60) working days, where prototypes were subjected to a dry run and simulation period of two (2) weeks continuous operation. The actual operation cycles of the prototypes in accordance with the varying room temperatures throughout the day was also observed during this period, testing them on a varied number of parameters, namely: operation time, turn on times in terms of fan speed control mode and motion sensitivity tests. Evaluation results revealed that the project functioned according to its lofty expectations where it was determined that it was the appropriate design that integrated the most practical and adaptable configuration for the intended application. It is in this line that intelligent or smart ventilation systems have now matured, providing a cost-effective approach to managing hot and humid conditions.
