Wifi would probably overkill for this - a more appropriate way may be low cost sensor/transmitters
on one of the unlicensed UHF bands sending short packets every few minutes to one or more receivers,
depending on distance - the receiver could either be a PC or a data concentrator that bulks up the
data to send via wifi/GSM/GPRS etc.
