Melexis releases a product family designed for optical proximity and gesture detection systems in automotive environments. The MLX75030 and MLX75031 feature two simultaneously operating light measurement channels which can detect the active optical reflection from a target. The proprietary integrated, ambient light suppression makes these channels highly tolerant to background light interference. Two additional channels are available to measure ambient light to ensure operation up to 15Klux (MLX75030) or 20Klux (MLX75030). On system level, the MLX75030 and MLX75031 should be complemented by one or two LEDs and photodiodes, of any type, for active light detection.
Melexis shows a video illustration of how it works.
