Analog Devices Inc. MAX25202EVKIT Evaluation Kit
Analog Devices MAX25202EVKIT Evaluation Kit is a platform for evaluating the performance of the MAX25205 optical IR sensor in a typical gesture and proximity-sensing application. The MAX25205 enables a recognition of hand swipe left, right, up, and down, finger/hand rotation clockwise and counterclockwise, air click, and proximity detection, or linger-to-click gestures.
The ADI MAX25202EVKIT application circuit operates by illuminating the user’s hand with a precision-controlled IR light source and measuring the reflected signal with the MAX25205’s 6x10 (60 pixels) IR sensor array. The four-LED IR light source is PWM controlled with external FETs from the MAX25205’s onboard FET driver. The return signal is analyzed with an embedded microcontroller that interprets the gestures.
