Analog Sensor

More Information

An analog sensor is a device that measures a physical quantity and provides a continuous, analog electrical output signal that's directly proportional to the measured value. This output can vary continuously across a range of values, rather than being discrete or digital, like 0s and 1s.

Key characteristics of analog sensors:
1.Continuous Output: They produce a signal that changes smoothly with the measured quantity, unlike digital sensors which use discrete states.
2.Proportional Output: The output signal is directly related to the measured value, meaning a change in the measured quantity will be reflected in a corresponding change in the output voltage or current.
3.Analog Signals: The output signal is an analog signal, which means it can take on any value within a specified range, as opposed to digital signals that are restricted to discrete values.
4.Wide Range of Applications: Analog sensors are used in various fields, including industrial control systems, environmental monitoring, medical devices, and scientific research.
