PAJ7620F2: Integrated Gesture Recognition Sensor
General Description
The PAC7620 integrates gesture recognition function
with general I2C interface into a single chip forming an
image analytic sensor system. It can recognize 9 human
hand gesticulations such as moving up, down, left, right,
forward, backward, circle-clockwise, circle-counter
clockwise, and waving. It also offers built-in proximity
detection in sensing approaching or departing object
from the sensor. The PAC7620 is designed with great
flexibility in power-saving mechanism, well suit for low
power battery operated HMI devices. The PAJ7620 is
packaged into module form in-built with IR LED and optics
lens as a complete sensor solution
