Which Is The Most Commonly Used Technology In Occupancy Sensors
Occupancy sensors are devices that detect the presence of people in a room or area and automatically control the lighting or other systems accordingly. They are commonly used in commercial buildings, such as offices, schools, and retail spaces, to save energy and improve comfort. There are several different types of occupancy sensors available on the market, but the most commonly used technology is infrared (IR) sensors. Infrared sensors detect motion by measuring the infrared energy emitted by people and other objects. They work by emitting a beam of infrared energy and measuring the amount of energy that is reflected back. When a person enters a room, the amount of reflected energy changes, triggering the sensor to turn on the lights or other systems. One of the main benefits of IR sensors is their high level of accuracy. They can accurately detect the presence of people even in low light conditions and through walls, partitions, and other obstacles. This makes them ideal for use in ...
