SUMMARY

Light sensors operate by either generating electricity or altering the electrical characteristics of a component, allowing for measurable changes in a circuit. The discussion highlights the use of photodiodes as a specific type of light sensor, emphasizing their sensitivity and response time. The choice of light sensor depends on the required sensitivity, response speed, and budget considerations. Understanding these factors is crucial for selecting the appropriate light sensor for specific applications.

Can anyone tell me how does a light sensor work?

What type?

There are a few different mechanisms depending on how sensitive you need, how fast a response and how much you want to pay.
Generally the light either generates electricity or changes the electrical characteristics of an element in such a way that you can measure the change with a circuit.
