An occupancy sensor is a device that detects the presence or absence of people in a space and automatically controls lighting, HVAC systems, or security functions. It uses technologies such as passive infrared (PIR), ultrasonic, or microwave sensing to monitor movement or body heat. When occupancy is detected, the sensor activates connected systems, and when the area is vacant, it turns them off to save energy.
Occupancy sensors are very reliable for detecting the presence of people in specific zones or areas. These devices help integrate two different systems together to automate their functioning. With this mechanism, organizations limit the total energy consumption and reduce expenses.
