Design of an Inclined Plane Experiment Tool Using E18-D80NK Infrared Proximity and MPU6050 Accelerometer Sensors: An IoT-Based Approach

Abstract

Electronics plays an important role in science, especially in the development of laboratory equipment technology in schools, which is the main pillar in education. Current laboratory equipment still relies on manual operation, reducing measurement efficiency and accuracy. This research focuses on developing an IoT-based inclined plane measurement system that can display results digitally. The system utilizes IoT-based E18-D0NK proximity sensor and MPU6050 accelerometer to ensure more precise and efficient measurements. The main objective of this research is to establish the performance specifications and system design of the inclined plane experimental tool. This research is an engineering research that measures the inclined plane by the object launch method, using both direct and indirect approaches. Direct measurements were taken via a mobile phone screen, while indirect measurements assessed the accuracy and precision of the digital system compared to conventional methods. The data was analyzed with statistical and tabular analysis to provide an overview of the system's performance. The system used proximity sensors to start stop the movement and accelerometers to calculate the tilt angle. The MPU6050 sensor showed an average accuracy of 99.22% and an average precision of 0.991. This tool shows an average accuracy of 98.83% with an accuracy of 0.996.
