Ibsen推出的I-MON80D是一种FBG传感系统探寻检测器,是高分辨率红外光谱仪,可对FBG传感系统光谱实时光谱监测。
但I-MON80D是一种插在PCB上的器件,需要其它电路的支持。
Ibsen推出的另一款集成的I-MON400-USB,提供USB和数据采集软件。
可与PC机通信,不过数据形式与所需的数据不符,也不利于后续工作的扩展。
所以选用I-MON80D

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
