Hi folks, I’m Jon Mullen the Energy Evangelist. This month we are looking at lighting, and today we’re talking about occupancy sensors (so this will include a bit about heating as well).
Occupancy sensors can switch on, or off, the lights and heating in a room. They can take many forms and activate because of heat difference, CO2 or humidity differences, movement, or even when you scan a keycard and enter a hotel room!
But that is just the beginning. Complex systems can also be linked to reception booking systems. So when you walk up to reception and pick up your room key the heating and lights can already be turned on automatically in your room.
Or if you have a new system which is connected to the internet the heating could be switched on as you walk out of the office and your house will be nice and toasty when you walk through the front door.
But one thing you need to ensure is that the sensor is installed correctly and the field of vision / detection is not obstructed by furniture or a curtain, otherwise the device will not work correctly. These ideas are just the beginning for an automated office or household.
