The MLX71120KLQ-TU is an automotive-grade, advanced active infrared (AIR) sensor manufactured by Melexis. It is designed to detect human presence and movement, as well as highly reflective obstacles, making it suitable for automotive applications such as gesture recognition, occupant sensing, and access control. The device has a robust, wide lens that enables it to detect motion in environments with challenging glare, shadows, and low-light conditions. It is optimized for low power consumption and is packaged in a tiny, low-profile 8-pin QFN, making it suitable for use in space-constrained designs.
