Sensors are devices that detect current changes in the environment and based in this information they give commands to the appropriate controllers in the Smart HomeTM system in order for the desired application to be activated.
They can be widely applied in everyday life and are more and more often used in residential facilities as well as commercial buildings. They are predominantly used in controlling the lighting, measuring the temperature and for the alarm system. Every HDL sensor is multi-functional i.e. it can perform more functions simultaneously.
