PAJ7260u2手势识别传感器

资料

1.简介

手势识别传感器是一款集成3D手势识别和运动跟踪为一体的交互式传感器，传感器可以在有效范围内识别手指的顺时针/逆时针转动方向和手指的运动方向等。

该PAJ7260u2手势识别传感器是将手势识别功能与通用I2C接口集成到单个芯片中的PAJ7620U2。它可以识别13种手势，包括向上移动，向下移动，向左移动，向右移动，向前移动，向后移动，顺时针方向，圆周 - 逆时针方向，向下，向下，从左到右，从左到右。这些手势信息可以通过I2C总线简单访问。该PAJ7260u2手势识别传感器模块设计核心芯片为 PAJ7260u2，是一个支持与I2C协议通信的身体红外识别IC。传感器可以应用于各类互动交互艺术产品，试想一下，挥一挥手，打开台灯，挥一挥手，打开音乐。一切尽在弹指间。PAJ7260u2手势识别传感器特点：
