The M5Stack Microphone Unit is an omnidirectional sound sensor with MAX4466 amplification and adjustable analogue/digital output, ideal for sound detection, audio monitoring, and sound-activated control projects.
The M5StackMicrophone Unit 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 analogue and digital signals. It includes a built-in LM393dual 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.
