Microphone Unit (LM393)

Description

Unit MIC is a sound sensor equipped with an omnidirectional electret microphone. The signal is amplified and output through the MAX4466 microphone preamplifier. This amplifier effectively suppresses power supply noise and common-mode noise, providing high-fidelity sound output, making it suitable for use in noisy environments. This unit can output both analog and digital signals. It includes a built-in LM393 dual voltage comparator, allowing the comparison voltage threshold to be set by adjusting a 10K potentiometer. This sensor is ideal for projects involving sound-to-electricity conversion and sound-activated switches.

Features

  • Sound sampling/audio recording
  • Built-in MAX4466 microphone preamplifier
  • Omnidirectional, 52dB sensitivity
  • Analog and digital signal output
  • Built-in voltage comparator and adjustable potentiometer for threshold setting
