Motion sensors are often used to monitor the controlled area for occupancy and signal this information to a lighting controller, which then decides whether to turn on the light, or to dim up the light and by how much. The three most common types of motion sensors used for occupancy and intrusion detection are passive infrared (PIR), microwave and ultrasonic sensors.

Motion Sensors for Occupancy and Intrusion Detection
A motion sensor is a device that detects physical movement or senses occupancy within an environment. It is designed to capture the kinetics or presence of objects of interest, and convert the detected changes into control signals that can be used to automate the operation of other connected...
