Remote Data Logging with Cell-Phones and the Internet

Abstract

By means of the GSM cell-phone network and the Internet, data can be delivered from remote locations to anywhere in the world. Using this existing infrastructure can be an advantage over the more traditional point-to-point radio telemetry. An obvious use in speleology is the remote monitoring of long-term cave-based experiments or water levels and the progress of flood pulses. David Gibson outlines the principles.
