3D Gesture Sensor


CQRPAJ7620U2 is a 3D gesture recognition sensor with integrated PAJ7620U2 chip, PAJ7620U2 integrates the gesture recognition function and the universal I2C interface into one chip. It can recognize 9 gestures, including move up, move down, move left, move right, move forward, move backward, rotate clockwise, rotate counterclockwise, and waveform. These gesture information can be easily accessed through the I2C bus. PAJ7620U2 also provides built-in proximity detection for sensing objects approaching or leaving. PAJ7620U2 has great flexibility in power saving institutions. Compare with solutions like APDS-9960, this module is faster, more accurate, while recognising more gestures with higher anti-interference capability. It suits for low power applications such as smart home, robot interaction, etc.
