KY038  is sound detector module also called sound sensor Arduino.  This sound detector also called Microphone Module for Arduino. Some Applications like interactive voice switch and loudness level indicator is very suited for this module.

Features Arduino sound detector :

1. Detectable sound signal size
2. Built-in filter-rectifier circuit, DC signal output
3. Good sensitivity, built-in amplifier circuit, adjustable gain
4. Voltage signal for sound intensity can be obtained by AD conversion
5. Analog voltage signal output, signal amplitude VCC/2
6. Compatible for Arduino sensor interface.

Package Includes in Arduino sound detector :

1 x Arduino sound detector Module
