WiFi offers a data intensive communication link for IOT devices within a small physical area. It needs moderate power and imposes no direct charge on data. However there are coverage limitations especially in deep build up areas and at wider range. Connecting large number of WiFi enabled IOT devices to a WiFi router could have reliability issues but nevertheless it remains a popular and easy choice for IOT connectivity in most installations especially in home automation and small office buildings.
As with all SM01 modules, SM01-WIFI 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.
