What’s the difference between Occupancy and Vacancy sensors for lighting?

When should you use a vacancy sensor, and where is an occupancy sensor a better fit

On the surface, it may seem like vacancy and occupancy sensors perform the same task, of automating the process of turning off lights to save power. But there is a significant difference in how they work which affects our choices of where to deploy them as a tool for lighting and energy management.

This video from Lutron does a good job of quickly and clearly explaining the differences between the two types of sensors and provides useful suggestions for how you can pick the right solution for your room.
