Abstract
Leaving children unattended in a car for few moments; especially in hot atmosphere, can cause a catastrophic tragedy to occur. This paper presents HACC system to help in preventing tragic child death caused by hyperthermia using detection and control system inside car. HACC system has been accomplished by developing a phone application and a surveillance system connected together to monitor the temperature and the presence of a child inside the car. The system starts to measure temperature inside car via temperature sensor. At the same time, it checks constantly the presence of child inside car via motion sensor. When system detects the presence of a child and the temperature inside car reaches unsafe limit, it will alert the caregiver via smartphone application and allows him/her at the same time to take an action and open windows remotely. If there is no response from the caregiver, system itself reacts and windows will be opened automatically.
