我背疼。
我知道原因。这是因为你在家工作时姿势不好。
我用 obniz 做了一个设备，如果你的姿势不好，它会警告你，所以我将介绍它。
成品设备介绍
不良姿势是通过眼睛和屏幕之间的距离来衡量的。
一般来说，建议眼睛与屏幕之间的距离至少为 40 厘米。
因此，如果您的眼睛与屏幕之间的距离小于 30 厘米，红色 LED 会亮起，并且 obniz 显示屏会显示“您的姿势太糟糕了！！”
当眼睛与屏幕的距离为30到40厘米时，黄色LED灯亮，obniz显示屏显示“你的姿势不好！！”
当眼睛距离屏幕40厘米以上时，蓝色LED亮起，obniz显示屏显示“你的姿势真棒！！”。
此外，它旨在根据姿势向LINE发送有关姿势的消息。
作为奖励，如果您的姿势不好，您将收到一条鼓励您拉伸的消息和一个使用各种拉伸方法的网页的 URL。
当眼睛与屏幕之间的距离小于 30 厘米时
◆ 眼睛与屏幕距离为 30 至 40 厘米时
当眼睛与屏幕之间的距离为 40 厘米或以上时

转变
开关分为30cm以内、30～40cm、40cm以上的情况。在这种情况下，根据翻译，LINEbot 会向您发送有关您的姿势的消息。
之后，在模板中用LINEbot写出你想输出的文字，就大功告成了。
概括
它曾是怎样的？
它非常容易创建，因此请作为参考。
在这个流程中，LINE 频繁到达。我们认为，如果每 30 分钟随机测量一次眼睛与屏幕之间的距离，并通过 LINE 通知结果，将会更加实用。
