Sound sensor module for Arduino (OT725-D93)

High-quality sensor module as a separate sound sensor, can be used in combination with the Arduino platform or other systems.
The highly sensitive electret microphone provides the output signal analog or digital. The sound sensor can detect sounds from 50 Hz to 20 kHz.
