GeoCloud Nodes obtain readings from analog sensors, digitize them, and then transmit them via a cellular gateway to GeoCloud servers for processing and presentation. The use of nodes allows collection of measurements from a wide area and eliminates the expense and difficulty of installing and maintaining long runs of cable to centrally located data loggers.
