Difference between digital and analog sensors

ANALOG SENSOR

It produces continuous output signal or voltage which is proportional to quantity to be measured.

• It produces analog output.

• Quantities such as temperature, speed, displacement, pressure, strain etc. are analog quantities as they are continuous in nature.

DIGITAL SENSOR

  • It produces discrete digital output signal or voltage which is digital representation of quantity to be measured.

  • It produces binary output in the form of ones (1s) and zeros (0s).
