mmWave IWR - building automation


TI’s industrial mmWave solutions for building automation enable the detection and tracking of people both indoors up to 14m and outdoors at greater than 50m range. mmWave can be used for high accuracy occupancy detection, where the position and velocity of people can be used to trigger systems upon a person entering an area of interest, or moving in a particular direction. 

mmWave sensors use onboard processing to reduce false detection by ignoring signatures of static objects that are not of concern such as chairs and desks, and dynamic objects such as trees and fans. 

mmWave sensors provide high performance sensing that is environmentally robust to rain, fog, smoke, or ambient lighting. With no camera or optical lenses, mmWave is suitable for privacy-conscience applications.

IWR6843 mmWave sensor

Occupancy detection/people counting, and automated doors and gates
Motion detectors and IP network cameras
Benefits Track and separate multiple people simultaneously with a single chip sensor. Simplify solution by ignoring non-moving (static) objects like chairs and tables and filtering moving objects such as fans, curtains, or blinds. Use 3D height information from the sensor to determine the stance of a person and whether or not someone has fallen without the use of a privacy-invasive camera  Robust  detection and localization of slow moving people even in  cluttered outdoor areas with lots of movement from clutter like trees and shrubs.
