In today's world, sensors are everywhere!This paper proposes the use of motion sensors with Internet of Things (IoT) enabled devices to create smart Wireless Sensor Network (WSN).Normally, motion sensors act discretely to turn ON/OFF devices based on human/animal detection in the Field of View (FoV) of the sensor.However, by examining analog movement pattern from the sensor can reveal important information such as direction of travel and other valuable information about the underlying object movement.The analog wave pattern is processed via signal processing and time-series algorithm.Later, the processing outcomes fed machine learning algorithm to reveal the direction of a travel.The direction of movement is estimated with more than 95% of accuracy.In a test building site, multiple of such sensor modules are distributed throughout a building.These modules send incoming and outgoing movement data to the sensor fusion node connected to the data logging computer.The data pattern is carefully analyzed to optimize the energy usage of university hallways lights and other appliances.Furthermore, data analysis and automatic building lighting control is explored as a part of an upcoming summer scholarly activities.This project is involving group of undergraduate senior level students of our engineering technology program.Students got the exposure of prototyping a sensor module, 3-D printing, deployment consideration, embedded programming, and the sensor data management.
