Product Details

The MAX25405 is a low-cost, data-acquisition system for gesture and proximity sensing. Detection distance is improved by integrating a complete optical system consisting of lens, aperture, visible light filter, and a 6x10 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 of the MAX25405 operate by detecting the light reflected from the controlled IR-LED light source with an integrated 6x10-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.

This discrete light source is created externally with one or more FETs driven directly from the MA25405. The light source’s PWM duty cycle is programmable from 1/16 to 16/16. The LEDs are pulsed on one or more times in a programmable sequence repeated for every sample.

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