Design of Field Instrumentation and Noise Removal Techniques for Seismoelectric Measurements

The Do-It-Yourself geophysicist

“…Traditional sensors such as geophones may be directly wired to pins on the embedded processors, but while simple it often produces very poor performance. Adding an instrumentation amplifier and an external A/D device close to measurement will result in better utilisation of dynamic range and signal buffering (Dupuis et al, 2020). Combining a digital MEMS accelerometer with a conventional geophone allows very broadband measurement for seismic waves plus allows accurate measurement of tilt.…”
