The collection of data which is in the form of analog signal is the main challenge faced by any design engineer. Mechanism of collection of data is the basic building block of any closed loop system. DAS is used in the most of the mechatronics applications, automation, automobile applications, biomedical high accuracy measurement and monitoring devices, etc. Physical quantity to be measured in such applications is in the form of analog signal. It is to be converted and stored in digital form so that it can be acted upon by a processing and controlling unit. DAS is made of three major components: transducer, signal conditioner and processor. DAS which is made of these components leads to several technical issues such as complex wiring, hardware and programming due to use of DAS in complex applications, human errors, noise interference, etc. This paper reviews general report on the basics of DAS based on the different types of sensors and electronic components used for the signal conditioning, storage and distribution of the data. It will also review a case study that describes the ways to improve the present day Data Acquisition System.
