Sensors (Safety System)
An incident occurred in 2011, central locking system of BMW car was not open due to short circuit. The car was fully burnt and four people were died in car which included one general manager and three technicians, so to overcome with this problem we implement a sensor which is known as heat sensor. It is one types of safety system, whenever short circuit occurs in central locking system it senses the temperature during period of burning when temperature reaches to 80oC to 90oC, the locks automatically gets opened and when the heat stops sensing on it immediately the locks get closed.
