What are the differences between light sensors and motion sensors?

What are the differences between light sensors and motion sensors?

Light sensors detect ambient light levels, while motion sensors detect movement. They serve different purposes.

Can you give me examples of where each type is used?

Sure! Light sensors are often used in automatic streetlights, while motion sensors are common in security systems.

Which one is better for home security?

Motion sensors are generally better for home security as they can detect intruders, while light sensors are more for lighting control.

Are there any devices that combine both sensors?

Yes, some smart home devices combine both light and motion sensors to optimize energy use and enhance security.
