SparkFun Geophone - SM-24 1-axis, Flex / Force Wearable Technology This mini Temperature Controller isNeed to put your finger on the pulse of the Earth? Did I just blow your mind? A geophone works by translating ground movement into voltage, which can easily be read by a microcontroller. The SM 24 geophone element is designed to offer the highest performance in seismic exploration based upon field proven I O Sensor technology. Low distortion, combined with excellent specifications, provide high fidelity data. Basically, its a super low frequency
