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.
Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A sensor converts the physical parameter (for example: temperature, blood pressure, humidity, speed, etc.) into a signal which can be measured electrically.Sensor can be defined as an element that senses in one form of energy to produce a variant in same or another form of energy.
