Special Features

  • 【Acts Like a Microphone】Used to receive sound waves, display vibration images of sound, but cannot measure the intensity of noise.
  • 【Working Principle】The sensor has a capacitive electret microphone that is sensitive to sound. Sound waves cause the electret film inside the microphone to vibrate, resulting in a change in capacitance and a small voltage corresponding to the change. This voltage is then converted into A 0-5V voltage, which is accepted by the data collector through A/D conversion and transmitted.
  • 【Specifications】50Hz-15KHz. Three digital pins: Clock, Data and Left-Right (Word Select) Clock.
  • 【Note】This I2S MEMS microphone is bottom ported, so make sure you have the hole in the bottom facing out towards the sounds you want to read. It's a 1.6-3.6V max device only, so not for use with 5V logic.
