PublicationAbstract
In September of 2016 a new digital communications network for the Azores Civil Protection (SRPCBA) was inaugurated providing digital, voice and Ethernet LAN telemetry capabilities to the Centre for Information and Seismovolcanic Surveillance of the Azores (CIVISA). During 2017, the telemetry links from all monitoring techniques were reconnected to the new communication system. In 2018 the CIVISA has started the migration from analogue to digital seismic stations and this process allow to liberate few short period geophones. At the CIVISA’s Information and Communication Technologies Support group (SATIC), motivated by the availability of sensors, an instrumentation project was started with the objective of develop affordable digital data acquisition system (DAS) for geophones and a Wi-Fi telemetry to transmit seismic data to the Data Acquisition Centre (CAD) of CIVISA, in Ponta Delgada. The DAS design uses Do It Yourself (DIY) modules for Internet of Things (IoT) applications, microcontrollers and low power computer boards.
