The project Community Environmental Observation Network (CEON) was dedicated to the development of a free sensor network to collect environmental data (e.g. ground shaking, climate data). It was intended develop the proof-of-concept for a system allowing to collect dat with contributions from citizen, research institutions or public authorities like communities or schools. The collected data should lead to a large data basis which can be used for public information, research, and arts.
A prototype of an open design seismograph based on the Arduino Mega2560 microcontroller board and the BeagleBone Black single-board computer was developed. Most work went into the development of a sensitive analog to digital conversion to meet the needs of scientific data collection. Four stackable printed circuit boards (PCB) fitting onto the Arduino were designed:
