â¢ Transducers and sensors are physical devices that are used in electrical, electronic and many other types of gadgets and appliances. â¢ Transducers are used to convert one energy type into another while sensors measure energy levels and convert them into electrical signals that can be measured digitally.
in the broadest definition a sensor is an object whose purpose is to detect events or changes in its environment and then provide a corresponding output a sensor is a type of transducer sensors may provide various types of output but typically use electrical or optical signalsfor example a thermocouple generates a known voltage the output in response to its temperature the environment sensor is a type of transducer sensors may provide various types of output but typically use electrical or optical signals for example a thermocouple generates a known voltage the output in response to its temperature the environment
