  Piezo element ø20mm 7BB-20-6
Piezo element that can be used either to play sound or in reverse, to pick up sound / vibrations Extremly low build height. Requires external oscillator. When used to pick up sound, it's usually called a contact microphone. Resonant frequency: 6.3 kHz ± 600 Hz Impedance: 350 ohm @ 6.3 kHz Diameter: 20mm Thickness: 0.42mm
  Geophone - SM-24
Need 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, it's a super low frequency microphone for the ground. Perfect for all of your 2-D & 3-D seismic exploration needs with bandwidth from 10 Hz up to 240 Hz Tight specification, low-distortion geophone Extended spurious over 240 Hz, allowing full bandwidth at 2-ms sampling Sensitivity of 28.8 V/m/s
