This paper describes for maintaining the car's safety and security through critical action. We are unable to look after our own while we operate in ignorance. This gadget has an eye blink sensor built in and also collision alert through GSM module and notifies to the respective person. This sensor's output is made with Arduino .A GSM modem is a mobile phone substitute without the screen, keypad, and speakers. The owner and the driver can both be alerted when a driver is acting in an unsafe manner. Consequently, the creation of an embedded sensor-based system is the main topic of this paper.
