PAJ7620U2 gesture recognition sensor. It can recognize 9 gestures including move up, move down, move left, move right, move forward, move backward, circle-clockwise, circle-counter clockwise, and wave. These gestures information can be simply accessed via the I2C bus.
The PAJ7620U2 also offers built-in proximity detection for the purpose of sensing object approaching or departing. The PAJ7620U2 is designed with great flexibility in the power-saving mechanism. The PAJ7620U2 is designed to operate from 2.8V to 3.3V over -40°C to +85°C and the pull-up voltage for the I2C bus and interrupt line is from 1.8V to 3.3
