Sensors and its Smart Applications

Today?s day to days life is rising with new and smart technologies, where the sensors plays a vital and major role. In early days everything used to be manual where human work was mandatory. But now a day?s manual had become automatic with increase in the sensor terminology. History has shown that advancements in materials science and engineering have been important drivers in the development of sensor technologies. This paper mainly focuses on the sensor terminology and its applications which are commonly used in our day to day life. Generally with the emerging trends in the microcontroller like Arduino the effect of the application had became easy for sensor measurement. Here different sensor applications like ultrasonic sensor, Biometric sensor, motion sensor had been presented.
