Consumers use motion sensors almost every day, often completely concealed. They perform trivial technical tasks and support the consumer to achieve more comfort or safety. Most applications have become commonplace to consumers. Motion Detectors are the key to make it possible for technical devices to respond to conditions in their surroundings. When a movement is recognized by the sensor, it passes along a signal to activate or disable connected technical functionality. This feature is used in active control such as contactless interactions or passive control such as automated applications. For motion control devices, different technologies can be used. Traditionally passive infrared and radar technology have a proven track record for common motion detection applications such as door opening, light automation, intruder alarm or touchless switches. The sensors have adapted to industry requirements, which have become more demanding over the years. They have to prove their value with compact outlines for form and fit in scaled down devices. Often low power consumption is desirable for energy saving operation. The price must be economical in order to be competitive, and the motion detector must be suitable for high volume productions. With technology innovation, reliable performance, functionality and minimal false detection are the expectations desired by industry. Despite radar detector cost due to its advanced functionality, they are now also highly recommended for low-cost and simple motion detection applications. Recent innovations in the field of radar make the technology evermore desirable. Radar motion detector utilization is on the rise.
