Over the last two decades the electronic content in automobiles, busses and lorries has significantly increased. In contemporary cars it has reached a value of about 15–20% and it is expected to further increase to 35–40% due to legislation and environmental requirements resulting in violation of emission standards and fuel economy standards. The electromechanical system helps system controls to improve fuel economy and reduce pollutant emissions and in improving the comfort and safety of vehicle users. With the recent advances in microelectronics, many sensors are being used in wide variety of applications, particularly in automotive industries and can be considered as preferable choice for signal conditioning accuracy and integration. The sensor functioning becomes sophisticated as market trends and customer requirements increase, this leads to the requirement of more accurate and reliable sensing element. The flexible sensor interfacing circuit is an automotive grade IC designed to be used as a sensor interfacing equipment that can overcome such problem. L9966 IC is one such type of dedicated integrated chip. The work proposes the design of a flexible sensor interfacing module that can interface different sensors without modifying PCB Hardware.
