The Sound Sensor can detect the sound strength of the environment. The main component of the module is a simple microphone and LM393 level convertor chip. The sensor can provide both digital aswell as analog output.



  • Operating voltage 3.3V-5V
  • Outputs digital switching output (high and low level 0 and 1)
  • Operating current (Vcc=5V): 4-8mA
  • Microphone sensitivity (1Khz): 52-48dB
  • Microphone Impedance: 2.2KΩ
  • Microphone Frequency: 16-20Khz
  • Microphone S/N ratio: 54dB
