我有几个 100 个传感器记录设施中的温度。我想将录音存储到时间序列数据库中。为此，我正在查看 AWS 站点。与之相关的疑虑/问题：
1. I have Arduino's with temperature sensor on the top of it. Can Gateway/Connector of Sitewise pick the data from arduino's? If not, what do we need in between arduino's and site-wise gateway?
2. Why do we need Gateway? How is it different from Connector?
