Analog Devices / Maxim Integrated MAX25405 IR Gesture Sensor

Analog Devices MAX25405 IR Gesture Sensor is a low-cost, flexible gesture-sensing solution for automotive applications. The MAX25405 integrates a complete optical system including lens, aperture, visible light filter, and a 6×10 photodetector array.

The MAX25405 recognizes the following independent gestures:

Hand swipe gestures (left, right, up, down, wave)
Air click
Flicks
Finger and hand rotation (clockwise and counter-clockwise)
Multizone proximity detection
Linger to click

The proximity, hand detection, and gesture recognition functions operate by detecting the light reflected from the controlled IR-LED light source with an integrated 6×10-element optical sensor array. The MAX25405 can detect these gestures even when exposed to bright ambient light. A low-power, low-cost CPU, such as the MAX32630, is required to process the data from the sensor.

Analog Devices MAX25405 supports two different serial communication protocols, the I²C (400kHz) and SPI (6MHz). The MAX25405 is housed in a 4mm x 4mm, 20-pin, optical QFN package.
