APDS9960 RGB Gesture and Proximity Sensor Module

This single chip packs three genuinely distinct sensing capabilities that would otherwise need three separate sensors: gesture recognition via four directional photodiodes that detect the direction of a hand swipe (up, down, left, right), ambient RGB color sensing, and proximity detection - all read over one I2C connection. That combination is specifically what makes touchless gesture control possible without a camera and computer vision pipeline, just a small sensor and lightweight interrupt-driven logic.

UV and IR blocking filters keep the RGB color readings accurate under normal lighting rather than skewed by invisible wavelengths, and a 32-sample FIFO buffer captures gesture motion data fast enough to reconstruct a swipe direction from a short sequence of readings. An interrupt pin means the host microcontroller only needs to react when a gesture or proximity event actually happens, rather than continuously polling the sensor.

Common uses are touchless gesture-controlled interfaces (swipe to skip a track, wave to dismiss a notification), ambient color-matching projects reading real-world object colors, and proximity-based wake/sleep triggers for battery-powered devices.
