IR Gesture 2 Click as its foundation uses the MAX25405, a data-acquisition system for gesture and proximity sensing from Analog Devices. This Click board™ represents an infrared-based dynamic optical solution that can sense a broader range of motions at extended distances. The MAX25405 detects broader movement proximity and doubles the sensing range to 40cm compared to earlier generations. It recognizes the following independent gestures: hand swipe gestures (left, right, up, down, wave), air click and flicks, finger and hand rotation (clockwise and counter-clockwise), and multizone proximity detection.
Along with integrated optics and a 6x10 infrared sensor array, the MAX25405 also includes a glass lens which increases sensitivity and improves the signal-to-noise ratio. The proximity, hand detection, and gesture recognition functions of the MAX25405 operate by detecting the light reflected from the controlled IR-LED light sources (SFH 4248-VAW and SFH 4249-UV) driven directly from the MAX25405. It can also detect these gestures even when exposed to bright ambient light and process data from the sensor through a serial interface. The light source PWM duty cycle is programmable from 1/16 to 16/16, where LEDs are pulsed on one or more times in a programmable sequence repeated for every sample.
IR Gesture 2 Click communicates with MCU using the 12-bit SPI serial interface compatible with standard SPI, QSPI™, MICROWIRE™, and digital signal processors (DSPs), with a maximum frequency of 6MHz. This Click board™ also possesses an additional interrupt pin, routed to the INT pin on the mikroBUS™ socket, indicating when a specific interrupt event occurs, such as the end of a conversation sample sequence.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
