Hybrid Connectivity Bike Lock System: Integrating IOT And SMS For Enhanced Security

Abstract

In the evolving landscape of urban mobility, ensuring the security and safety of personal transportation modes
like bicycles and motorbikes has become paramount. This project presents a novel approach to bike security and
safety by integrating Internet of Things (IoT) technology with advanced sensing capabilities to create a robust,
dual-mode bike ignition and alert system. Utilizing the ESP32 microcontroller, featuring built-in WiFi and
Bluetooth, the system allows real-time control and monitoring through a connected IoT platform. In scenarios
where WiFi connectivity is unavailable, the system transitions seamlessly to GSM-based SMS communication
using the SIM900A module, ensuring uninterrupted operational capability. The enhanced system incorporates an
ultrasonic sensor to detect nearby obstacles, triggering a buzzer to alert the rider of potential hazards, improving
situational awareness and safety. Additionally, a smoke sensor continuously monitors for the presence of smoke
or harmful gases around the bike, further enhancing security by alerting the user to potential fire hazards or
tampering attempts. The system's primary control mechanism involves a secure mobile application that facilitates
the locking and unlocking of the bike ignition via internet commands or SMS, while also providing alerts from the
integrated sensors. This innovative combination of IoT connectivity, environmental sensing, and traditional
communication methods not only modernizes bike security but also elevates safety standards, offering users a
comprehensive solution for both protection and peace of mind in their daily commutes.
