The external temperature data allows our system to understand whether it is cold or warm outside, determining the level of heating required. Additionally, the occupancy data allows our system to know whether a room is being used or not, again, allowing it to make changes accordingly. This would be of great benefit in your toilets, offices or areas of the building that are not used as regularly. Our occupancy sensors turn the lights off and the heating down when they sense that an area is no longer in use. Eventually, the heating will be turned off, saving you energy and money.
