Anna has been told that her organization has deployed microwave sensors in the organization’s warehouses. What are microwave sensors most frequently used to detect?

Microwave sensors are commonly used to detect motion and have advantages over infrared sensors because they can work in a greater temperature range as well as traveling through some obstacles that would not allow infrared to penetrate them. They do not capture audio and are therefore not used for glass-break sensors, they do not capture thermal data like infrared sensors, and they are not pressure sensors.
