    Just as a "heads up", if you try to compare the pressure measured with that reported by, say, the National Weather Service, you'll probably see a lower reading on yours than on theirs. That's because they normally adjust their readings for altitude, and unless you happen to be within a hundred or so feet of mean sea level, the difference can be substantial.

    For my sensors, I've implemented Babinet's Formula to correct for this -- see this for details. (It also requires the "mean temperature", but I just use the current temperature value.)

    If you wish to have multiple "transmitters" and/or multiple "receivers", I would suggest investigating something called "MQTT" as a data protocol. At least, that's what I use, with the "broker" running on a Raspberry Pi.
