What is a  Sensor ?

Sensor Definition

A sensor is a device that responds to changes in physical phenomena or environmental variables, converting them into readable signals.

Sensor Calibration

Sensors need calibration against a reference value for accurate measurements.

Active and Passive Sensors

Active sensors generate power within themselves, while passive sensors require an external power source.

Types of Sensors

• Temperature

• Pressure

• Force

• Speed

• Light

Electrical Sensor

Sensors that detect and measure electrical properties, converting them into usable signals for analysis.
