Occupancy Sensing

the foundation of every home automation system

Why occupancy sensing?

Smart building automation is gathering real momentum in both home and commercial markets, offering increased levels of occupant comfort, security, and energy efficiency. With global energy demands rising inexorably and power companies struggling to meet them, energy saving strategies are taking centre stage.

Using occupancy sensing to automatically turn off task lighting and electrical appliances when they’re not being used by building occupants achieves more though than just conserve power and cut energy bills, it helps to reduce carbon emissions, and prolong the life span of all kinds of equipment.

What is occupancy sensing?

Reliable and accurate occupancy sensing has long been the foundation of the smart-automated home or office. Occupancy sensors detect whether an indoor space is being used by someone or not and is programmed to automatically turn electrical systems on or off, such as lighting, heating, ventilation and other equipment.

The majority of existing occupancy sensing solutions however fail to detect stationary occupants and have high rates of false tripping.

To be reliable, occupancy sensors need to be sensitive enough to detect even the slightest human movement; the breathing chest of someone sleeping, the heartbeat of a person sitting still.

How do we do occupancy sensing?

Occupancy sensing answers a very simple question: Is there a person present or not? Presence can be detected from someone walking through a room, or someone just sat down using a keyboard – it can be a major movement, it can be a minor movement.

TransRobotics ultra wide band radar technology uses the pulse Doppler shift principle to separate human movement among static objects such as walls, desks and chairs. Even tiny movements like a person’s breathing can be detected.
