Abstract

An acquisition system has been developed as an evolution of the gDT316 and gCNT16 dataloggers [1]. This new datalogger, gDT524, has several advantages in comparison with the previous versions. The main features, beside the low power consumption and low cost, are: an A/D converter with 24 bits fivechannels inputs, two 16 bits counters, meteorological sensors, real time clock with synchronization over NTP, micro-SD storage and GPRS communications through any standard modem with AT commands. Here we describe this device, developed in order to acquire low rate parameters related with volcano activity.
