Smart Bicycle Speed and Location Monitor

This study presents the design, development, and evaluation of a Smart Bicycle Speed and Location Monitoring System aimed at enhancing the safety of young cyclists through real-time monitoring and parental notification. The system integrates a Hall Effect sensor for accurate speed detection and a GPS/GSM module for continuous location tracking. Speed and location data are transmitted via GSM short message service (SMS) to a parent’s mobile device, including automated alerts when predefined overspeed thresholds are exceeded. Field testing conducted in urban and suburban environments demonstrated a mean speed measurement accuracy of 98% with a maximum deviation of ±0.3 km/h, and GPS positional accuracy within ±5–10 meters. The results indicate that the proposed system provides a reliable, low-cost, and practical IoT-based solution for improving youth cycling safety and parental supervision.
