The number of automobile sensors is increasing continuously because of their proved benefits represented in avoided accidents, higher driving efficiencies, and ubiquitous sensing-based services. These benefits are not limited to only the vehicle’s driver, but also to other vehicles and third parties. Sensors also control vehicle emissions and make vehicles more comfortable and efficient. In this article, we categorized different types of sensors and their function. We also developed a concept that shows how automobile equipped with sensors can be considered as essential mobile resource of sensory data and sensor-related application. In addition, we categorize automobile sensors along the area that support ITS application and communication technologies. The responses of these sensors in an automobile has resulted in high efficacy in the area of safety, movement and environment. Each sensor is activated by the Electronic Control Unit when it receives an electrical signal between 2- 5V and send information to the actuators that performs work. Results obtained have shown increased performance in the response time to activities of the driver while driving
