- M5Stack Microphone Unit (LM393)
- Offers two LEGO compatible holes
- Built-in Omni-directional electret microphone
- Provides digital output and analog signal
- Features omnidirectional, 52dB sensitivity
- Development platform: Arduino, UIFlow (Blocky, Python)
The M5Stack Microphone Unit (LM393) is a sound sensor with a built-in Omni-directional electret microphone. The signal is amplified and output by microphone preamplifier max4466.
The built-in LM393 double voltage comparator can set the comparison voltage threshold by adjusting 10K adjustable resistance. The sensor is very suitable for acoustic electrical conversion, audio recording/sampling, FFT acoustic feedback, voice switch, and other projects.
Applications
- FFT Spectrum Display
- Audio Sample/Record
- Voice Switch
