Innovative Design and Construction of a Raspberry Pi-Based Smart Ground Clearance Measurement System for Automotive Safety
Abstract
Ground clearance is one of the vehicle dimensions regulated under Indonesia's motor vehicle type approval testing regulations, with a permissible tolerance of ±50 mm from manufacturer specifications. The current manual measurement procedure requires inspectors to crouch beneath the vehicle, thereby posing occupational safety risks and reducing operational efficiency. Previous studies have developed prototype ground clearance measurement tools; however, these prototypes lack real-time remote monitoring capabilities and data logging functionality. Fundamentally, this study endeavors to conceptualize, develop, and operationalize a Raspberry Pi-driven measurement system for ground clearance assessment, embedded within an Internet of Things (IoT) architectural framework. The device employs the US-015 ultrasonic sensor as the primary measurement component, a Raspberry Pi as the central processing unit, and an ESP32 module for wireless data transmission via the MQTT protocol to the ThingSpeak IoT platform, enabling measurement results to be monitored in real time through a web-based dashboard. Driven by its core research objectives, the present investigation positioned itself firmly within the Research and Development (R&D) methodological tradition, drawing upon the ADDIE model as a holistic developmental construct that cohesively structured and steered the advancement of every constituent research phase. Performance testing was conducted on 30 freight vehicles at the UPT PKB (Vehicle Roadworthiness Testing Unit) of Kediri City. The test results demonstrate a mean accuracy of 98.63%, with a mean error rate of 1.37%. Time efficiency evaluation reveals a reduction in measurement duration of 40.25%–45.16% compared to the conventional manual method. Five certified expert validators assessed the device and collectively awarded a score of 90%, confirming its classification as 'Highly Feasible' for operational use. This device offers a safe, efficient, and IoT-connected solution for ground clearance measurement in motor vehicle type approval testing.
