How Sensing Circuit Work?

Light Sensors. A Light Sensor generates an output signal indicating the intensity of light by measuring the radiant energy that exists in a very narrow range of frequencies basically called “light”, and which ranges in frequency from “Infra-red” to “Visible” up to “Ultraviolet” light spectrum.

What is sensing circuit?

A current sensing circuit or board monitors electronic current flow in a number of applications. ... This is often referred to as “shunt resistor current measurement.” The current sensing circuit creates a proportional current or voltage output to the current in the path being measured.

How do sensors work?

How do sensors work? ... Put simply, a sensor converts stimuli such as heat, light, sound and motion into electrical signals. These signals are passed through an interface that converts them into a binary code and passes this on to a computer to be processed.
