Sensors play a key role in any automation and control systems. Sensor is a device that measures a physical quantity and converts into a signal that can be easily read by the instrument used. It gives a detailed description of the given object. There are uncountable application of sensors which includes aerospace, medicine, manufacturing, robotics, machine and cars.
Newly designed sensors utilize advanced techniques making it more efficient and smaller in size. In addition to this, these sensors collect information much more than the capability of traditional sensors. Traditional sensors were wired but these newly designed sensors are wireless which adds one more key feature of such sensors.
