Development of an automatic vehicular heatstroke detection system

The cases of children being left in a car and died of heatstroke are on the rise every year. Car manufacturers have not implemented any sort of alert system that could prevent these unfortunate events from happening. There are many baby car seat alert systems available in the market, however, they are mostly inconsistent and unreliable. There is a need for more effective and efficient alert system to remind the users of their forgotten child. This paper aims to provide solutions to caretakers through application of multiple sensors for integration of a child detection system and also to discover the best placement of the sensors for a more effective system. The selection method is based on experimental setup with a test subject which is a human being. A prototype for the detection system is fabricated and results show a combination of ultrasonic and motion sensors produces the best results. The best position to place the ultrasonic and motion sensor is determined to be above the child seat and in the middle of the car respectively. The prototype of the detection and alert system is validated via a set of assessments to determine its accuracy, adaptability and reliability.
