Sensor\types of sensors\working principle\Transducers\Actuators\proximity switches(sensors). what is sensors? A sensor is a device which converts a physical event into an electrical signal.or Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. working principle Every sensor has different principle of operation, based on the type of physical quantity it is measuring. The idea is to create a change in the property/properties of sensor (such as resistance, density, shape, temperature etc) as a function of the physical quantity under measurement. classification of the sensors they are divided into two part Active and Passive sensor. active sensor - Active sensors have its own source of light or illumination. In particular, it actively sends a pulse and measures the backscatter reflected back to the sensor .EX- The r...
