There are many different types of sensors surrounding us everywhere we go. Sensors play a significant role in improving our lifestyle, enabling automation and productivity. The smartphone that almost everyone is holding today has more sensors than it used to have. Microphone, camera, accelerometer, compass, light sensors, etc…
A sensor is a device that is able to convert physical information into an electronic signal.
A sensor is designed to convert the information from our environment using the law of physics, converting them into useful information for processing. With the improvement in technologies, more and more types of sensor are created. Let us look at the list of sensor technologies, followed by the name of the sensors use in the common application.
