APDS9960 Proximity, Gesture, RGB And Ambient Light Sensor

 

As part of my research for a larger project (coming soon), I stumbled across this small $5 sensor that can provide proximity, gesture sensing and RGB + ambient light levels.  And all this with only 3 GPIO pins on the ESP32.  And it can be used with both Arduino/C++ sketches or in ESPHome for you Home Assistant users.
