产品简介
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.
