通信模块采用无线通信模块，例如，GPRS模块、4G模块等，本实施例中，采用深圳市金鸽科技有限公司生产的Sensor To Cloud系列传感器物联网终端，Sensor To Cloud系列传感器物联网终端可选GSM、GPRS、3G、4G、NB-IoT、LoRa、以太网等多种通信方式，便于将数据传送至云平台。
这里，要说明的是，本实用新型涉及的功能、算法、方法等仅仅是现有技术的常规适应性应用。因此，本实用新型对于现有技术的改进，实质在于硬件之间的连接关系，而非针对功能、算法、方法本身，也即本实用新型虽然涉及一点功能、算法、方法，但并不包含对功能、算法、方法本身提出的改进。本实用新型对于功能、算法、方法的描述，是为了更好的说明本实用新型，以便更好的理解本实用新型。
最后需要说明的是，上述描述为本实用新型的优选实施例，本领域的普通技术人员在本实用新型的启示下，在不违背本实用新型宗旨及权利要求的前提下，可以做出多种类似的表示，这样的变换均落入本实用新型的保护范围之内。
