German manufacturers ELMOS launched LED lighting gesture recognition chip

Germany Dortmund, Germany aiermosi semiconductor company (ELMOS) recently announced the launch of a gesture recognition for non-contact photoelectric sensor chip E527.16. The chip is based on the principle of HALIOS: a LED tube emits modulated infrared light, infrared light when they encounter objects, one part is reflected back and photoelectric tube system receive into electrical signals. At the same time, another LED tube at the same time emit the same amplitude, but the phase difference of 180 infrared light. In normal operation, it can ensure that the amplitude of the signal is the same as that of the opposite phase, and the output signal of the circuit is always zero. The biggest characteristic of the optical system designed by this principle is that it can resist the strong interference of the external environment, and the performance is not affected by temperature and light.

The chip can be identified, and close to the fast swinging and other flapping gesture recognition by these actions, output various working condition, the detection distance up to 25cm. To recognize the gesture is included in the effective detection range: trigger gesture objects (such as hand) into the effective detection area of the system; pat gestures, vertical direction fast moving back and forth to simulate a virtual switch; timing gesture stop for a certain time; wiping, sliding speed in horizontal direction with certain gestures; close gestures, to a certain speed slow close to or away from the sensor. In addition, the output of the working conditions include: open and close, all bright lights or all out; dimming, the brightness of the lamp can be adjusted from 0% to (KE3 diao4 _bu4). At the same time, by changing the brightness of the lamp to inform the user that the system has identified a gesture.

The chip has HMI man-machine interface, control chip integrated gesture recognition and dimming of the most basic, the user does not need to add additional MCU and complex software, is a complete function of gesture recognition solutions, applicable to all types of lighting applications, or gesture sensing products widely applied to a variety of switches, detect objects, such as dimming in non-contact. In addition, the gesture recognition solution is reserved for users with a certain amount of space, according to the actual needs of some personalized design and optimization.
