Non-contact IR sensors detect occupancy even when stationary
Omron Electronic Components has introduced a non-contact MEMS thermal sensor that can reliably detect the presence of humans in an area without the need for movement. The ultra-sensitive sensor is an outstanding alternative to pyroelectric sensors or PIR detectors in home automation, building automation, healthcare, security and industrial applications.
The new Omron D6T is a super-sensitive infrared temperature sensor that makes full use of proprietary Omron MEMS sensing technology. Most human presence sensors rely on movement, but the D6T is able to detect occupation by sensing body heat and provides a more reliable basis for switching off lighting, air conditioning and other services when the space is empty. Conventional sensors often fail to distinguish between an unoccupied space and a stationary person. This feature is a particular issue in healthcare system design, when detecting the presence of bed-bound patients in a room.
