Occupancy Sensors: The Smart Solution for Energy Efficiency
What is an Occupancy Sensor? An occupancy sensor, also known as a motion detector or presence detector, is a device that detects the presence or absence of human beings or other living creatures within a designated space. These sensors are designed to automatically control lighting, HVAC systems, and other electrical equipment based on the occupancy status of the area. How Do Occupancy Sensors Work? Occupancy sensors employ various technologies to detect movement or presence. Some common methods include: Infrared (IR) Sensors: These sensors detect the infrared radiation emitted by human bodies. They are sensitive to changes in temperature and can accurately determine if someone is present. Ultrasonic Sensors: Ultrasonic sensors emit high-frequency sound waves that bounce off objects and return to the sensor. By measuring the time, it takes for the sound waves to return, the sensor can determine the presence of objects, including people. Microwave Sensors: ...
