In order to use the touchless switch, the user places a finger, hand, foot, or other object in front of the radar device. The IMD-3000 will recognize every small movement independent from the direction or the type of movement, so the user can also do a hand wave within the detection area in order to trigger a short impulse. Movements outside the detection range will be ignored. The performance of the detection is unaffected by object coverings, like gloves. Then, the impulse is forwarded to a linked device in order to activate a technical function; for example, switching on or off a light. A special feature is the opportunity to learn in changing environments. For example, a placed piece of chewing gum or a not perfectly fitting enclosure will be learned as a static object and is ignored for further detection.
