The MAX25205 is a low-cost data-acquisition system for gesture and proximity sensing. The MAX25205 recognizes the following independent gestures:
- Hand swipe gestures (left, right, up, and down)
- Finger and hand rotation (CW and CCW)
- Proximity detection
The proximity, hand detection, and gesture recognition functions of the MAX25205 operate by detecting the light reflected from the controlled IR-LED light source with an integrated 6x10-element optical sensor array. The MAX25205 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 MA25205. 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 that is repeated for every sample.
For flexibility, the MAX25205 supports two different serial communication protocols: I2C (400kHz) and SPI (6MHz).
The MAX25205 is available in a 4mm x 4mm, 20-pin, optical QFN package.
