When low power consumption and longer range are desirable in an application, wireless mesh offer a solution to connect sensors. One mesh device can communicate to another and then the other communicates to another, until the messages reaches mesh gateway which converts it into TCP/IP for connection to the cloud. Mesh cannot guarantee low latency due to number of hops but it is an extremely useful option to build a cluster of local IOT devices. The low power consumption means that a battery powered IOT device can last for years which is not the case with other connectivity options.
As with all SM01 modules, SM01-MESH module has identical microcontroller, hardware add-ons, expansion connector, and provided with appropriate software libraries which enables application code migration seamless across all SM01 series.
