Sensor selection method for IoT systems - Focusing on embedded system requirements

Abstract

Recently, various types of sensors have been developed. Using these sensors, IoT systems have become hot topics in embedded system domain. However, sensor selections for embedded systems are not well discussed up to now. This paper focuses on embedded system's features and architecture, and proposes a sensor selection method which is composed seven steps. In addition, we applied the proposed method to a simple example - a sensor selection for computer scored answer sheet reader unit. From this case study, an idea to use FTA in sensor selection is also discussed.
