For designing and knowing the work, we need to know the sensor types and it working. Even daily usage of mobile contains sensors like hall sensor, proximity sensor, accelerometer sensor, touch screen, microphone etc., There are plenty of sensors available and each have different characteristics, Sensor definition: The sensor can be defined as a device which can be used to sense/detect the physical quantity like force, pressure, strain, light etc and then convert in to desired output like the electrical signal to measure the applied physical quantity. (input)----> sensor---->Signal detecting---->(output) Various sensors have different operating ranges which should be considered while working...
