I am looking for a cheap way to collect weather data in a remote area. Temperature, humidity and rain are the minimum requirements for data collection.
Because only mobile phone coverage is available, I need to plunk a simcard in it or use a USB modem thingy (which I have).
That said it is a 3G cellular modem device and some carriers like Verizon and AT&T will be shutting down 3G service in the next couple years. Ecowitt has said that they are working on developing a 4G version but that may not be out for a year or more. No ETA on this. You would most likely be able to upgrade the modem when it becomes available… no guarantees.
