我有一个DS18b20传感器连接到我的pi。我正在使用CRUD网站添加存储在MongoDB中的姓名，姓氏和电话号码。如果温度高于或低于特定水平，我想使用来自原始数据库的数据发送电子邮件警报。我可以正常工作，但我也想在电子邮件中包括实际温度以及数据库中的详细信息。我得到了数据库的详细信息，但是温度让我不寒而栗！我正在运行多个流程，这是我的CRUD网站和数据库的流程，然后是我如何将所有内容整合在一起的方法。
调试输出：Temperature Alert! testing tillblue Temperature is [object Object] Thu Mar 21 2019 01:26:26 GMT+0200 (SAST)
我想将我的DS18b20值插入“ [object Object]”部分。
（测试tillblue是来自MongoDB Crud站点的值）
如何填充？
