警猫眼Arduino源码分享，把闲置手机变成安防监控摄像头！
现如今智能手机更新换代太频繁，换下来的旧手机卖二手不值钱，丢弃又觉得可惜，而且产生电子垃圾污染环境。怎么办？？？在这里要推荐一个变废为宝的好办法，就是通过安装一个免费的“警猫眼”的App，把闲置旧手机变成专业网络摄像头，即经济又环保！！！
使用方法：
第一步，在闲置的安卓手机上运行“警猫眼”摄像端程序，布防，如果能联网会自动分配一个摄像端ID并显示在标题栏。
第二步，在另一台手机或电脑上运行“警猫眼”观看端程序，添加第一步的摄像端ID，即可连接。

连接后摄像端手机的摄像头会被打开，你把它放置在你想监控的地方，只要有网络，无论距离有多远，你就可以在另外一台手机里看到实时画面，而且比QQ视频还要更流畅，此外它还提供包括动作监测、双向语音、以及24小时SD卡录像等其他功能。
摘录官方网页的介绍：

“警猫眼”软件把闲置安卓手机变成智能网络摄像头，可通过WiFi/3G远程传输实时视频与音频至随身手机，好似千里眼、顺风耳。附加摄像头动作捕捉、入侵报警，以及24小时无间断录像。专为居家室内安全系统设计。
▶ 无需专业监控硬件，只要一台闲置安卓手机 + 免费的“警猫眼”软件！
▶ 可用随身手机和电脑远程观看，观看端有Android、iOS、PC电脑 三个版本！
▶ 无需路由器端口设置，P2P即插即用！
▶ 没有内网限制，只要上互联网就能远程监控！
▶ 支持H.263硬编码、H.264硬编码，最大程度利用你安卓手机的潜能！
▶ 摄像头图像移动侦测触发报警，声音侦测触发报警，手机被拿动触发报警！
▶ 不插手机卡时，可以电子邮件报警；插手机卡时，还可以短信、彩信、打电话报警！

很明显，能看出来 “警猫眼”机底盒是 Arduino控制板为核心的，还有HC-06蓝牙模块，DHT11，MQ2，舵机，继电器，红外人体感应器，LED灯，等模块。。
“警猫眼”机底盒与上面的安卓手机 是通过蓝牙串口通信交互的。
