  • Breakout Board for Electret Microphone with op-amp

      Breakout Board for Electret Microphone with op-amp
    This small breakout board couples an Electret microphone (100Hz10kHz) with a 60x mic preamplifier to amplify the sounds of voice, claps, door knocks or any sounds loud enough to be picked up by a microcontrollers analog-to-digital converter. Each breakout comes fully assembled and works from 2.7V up to 5.5V.The Electret Mic Breakout translates amplitude (not volume) by capturing sound waves between two conducting plates (one a vibrating diaphragm and the other fixed) in the microphone and converting them into electrical waves. These electrical signals are then amplified and picked up by your microcontrollers ADC.

  • Geophone - SM-24

      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
