SafeLifeCar: solução open source de baixo custo para segurança de veículos.

Abstract

The alarming number of deaths of infants, children, and pets due to heatstroke and/or asphyxiation, often resulting from being forgotten in parked vehicles, reveals a critical vulnerability in automotive safety. Such incidents can be attributed to multiple factors, including stress, fatigue, and changes in routine. In this context, SafeLifeCar was developed: an open-source, low-cost project based on Internet of Things (IoT) principles, aimed at preventing or significantly reducing such tragedies. The prototype’s core requirements include energy autonomy, wireless connectivity (via Wi-Fi or mobile hotspot), and real-time collection of temperature, humidity, and vehicle speed data, in addition to continuous geographic location tracking. The collected data are processed to generate immediate alerts, which are then transmitted to a communication bot on Telegram. Validation through practical testing demonstrated the system’s effectiveness in detecting critical conditions, such as the combination of high internal temperature and the presence of occupants in the vehicle. In such cases, the system automatically sends alerts to the user, even in scenarios with limited network connectivity, enabling timely preventive actions and contributing to the reduction of fatality risks.
