SENCAR Smoke Detection System.
Developing an AI-powered smoke and odor detection system for rental car fleets using embedded AI chips and IoT sensors with 15-30 seconds detection accuracy.
Project Overview
SENCAR, a leading private rental car company in Ho Chi Minh City, partnered with AlphaBits to develop and test an innovative AIoT prototype for their fleet management. The project focused on creating an embedded AI system capable of detecting smoke and specific odors (including durian) in rental vehicles with high accuracy and reliability.
Our solution involved developing a prototype using cutting-edge AI embedded chips that could provide real-time detection within 15-30 seconds while maintaining continuous monitoring for extended periods. This technology addresses critical fleet management challenges including vehicle damage prevention, customer safety, and policy enforcement.
Key Challenge
SENCAR needed a reliable, automated system to detect smoking and strong odors in their rental vehicles to maintain fleet quality, ensure customer satisfaction, and enforce rental policies without manual inspection of every vehicle return.
