SeismoBot is an open-hardware data acquisition system for sampling from geophones. Geophones are typically used by geologists to record seismic activity, but they can be used to record low-frequency motion from a variety of sources. Geophones have been used to map out the structure of the Earth, measure sleep quality, and detect changes in urban activity during the COVID-19 pandemic.
SeismoBot is a Raspberry Pi HAT which features analog signal conditioning, a 24-bit ADC, and a microcontroller to orchestrate the conversion. The data can be saved to the Pi's SD card, processed for feature detection, or uploaded to the cloud for offline analysis.
Seismobot is the first open-hardware system of its kind. The board design files and firmware code are available on GitHub under the terms of the CERN OHL.
