Scalar sensor vs Vector sensor | Difference between Scalar sensor and Vector sensor

This page compares Scalar sensor vs Vector sensor and mentions difference between Scalar sensor and Vector sensor.

Scalar sensor

• The sensor which produce output signal/voltage which is proportional to magnitude of quantity to be measured is known as scalar sensor.
• Temperature of a room is measured using scalar sensor (i.e. thermometer or thermocouple) which measures temperature changes irrespective of sensor orientation. • Examples:
Temperature sensor, Color sensor, pressure sensor, strain sensor etc.

Vector sensor

• The sensor which produce output signal/voltage which is proportional to magnitude, direction as well as orientation of quantity being measured is known as Vector sensor.
• Acceleration of body is measured using accelerometer which measures component of acceleration of body with respect to x, y, z coordinate axes.
• Examples:
Sound sensor, image sensor, velocity sensor, acceleration sensor etc.

➤The major difference between scalar sensor and vector sensor is based on type of data to be measured. As mentioned above, scalar sensor measures scalar data where as vector sensor measures vecror data.
