安心摸鱼？用微波运动传感器提前预警！🚀

鱼儿很美，摸鱼儿快乐

朝九晚五的长时间工作容易让效率变低，我们需要适当“微休息”，上班时间摸鱼就是一种 “微休息行为”，是一种针对心理资源的管理策略。劳逸结合，调节心态，通过短暂的微休息行为来恢复我们整个工作中消耗的心理资源，并获得更多的积极情绪，所以，我认为一定能促进工作效率呢。

但是，大多数领导们对于这种上班行为当然是看不惯，因为很可能不能按时完成工作任务啊。

所以“摸鱼”时，我们的内心一定不可能安定！

为此，这里推荐用“微波运动传感器”来检测我的周围环境动态，做到提前预警，随时切换到工作状态！

查阅到微波运动传感器的优点如下 ~

微波探测方式与其它探测方式相比：
非接触探测；
不受温度、湿度、噪声、气流、尘埃、光线等影响，适合恶劣环境；
抗射频干扰能力强；
输出功率小，对人体构不成危害；
探测距离远（本模块2-16米）；
支持对非生命类物体的检测；
微波的方向性很好，能够穿透任何非金属物体（很容易隐藏它），速度等于光速；
寿命长，大于100000小时，高可靠性、稳定性。
