Analog sensor vs Digital sensor | Difference between Analog sensor and Digital sensor
This page compares Analog sensor vs Digital sensor and mentions difference between Analog sensor and Digital sensor.
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.
• Example: Temperature of liquid can be measured using thermometer or thermocouple which continuously responds to
changes in temperature as liquid is heated up or cooled down.
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).
• Digital sensors overcome limitations of analog sensors counterpart.
• They are used in various applications such as waste water, water and other industrial processes.
• Digital sensor consists of sensor itself, cable and a transmitter.
• Examples: Measurements such as pH level,
conductivity, dissolved oxygen, ammonium, nitrate etc. are conducted using digital sensors.
• Refer analog signal processing vs digital signal processing >> for more information.
➤The major difference between analog sensor and digital sensor is based on their respective output. As mentioned above, analog sensor produces analog output where as digital sensor produces digital output.
