Smart Sensor-Based Rear Seat Monitoring System to Prevent Pediatric Vehicular Heatstroke

This research presents an innovative solution aimed at preventing in-vehicle pediatric heatstroke incidents through the integration of advanced sensors, connectivity, and intelligent algorithms. The proposed system continuously monitors crucial parameters including occupancy status, temperature, and the child's Respiratory Rate (RR). A hybrid detection approach, combining Force Sensing Resistor (FSR) sensors and motion sensors, is employed to ensure enhanced accuracy. To optimize the system efficiency, the solution utilizes Simplified Frequency Analysis (SFA), offering processing speeds up to 80 times faster than conventional methods, making it ideal for real-time applications. The processed data is seamlessly transmitted via a mobile application, enabling immediate caregiver notification and intervention. Initial testing confirms the solution's high accuracy in occupancy detection and breath monitoring, satisfying automotive standards for temperature resilience and power efficiency. Engineered to withstand extreme environmental conditions ranging from -40° to +85°C, while maintaining a minimal standby current of 104 µA, this technology holds immense potential in not only saving lives but also establishing itself as a standard safety feature.
