ماژول میکروفن با خروجی دیجیتال (سنسور صدا)

این ماژول شامل یک میکروفن است که با استفاده از پتانسیومتر موجود بر روی برد ماژول می‌توانید سطح صدایی که باعث تغییر خروجی ماژول می شود را تعیین کنید . با افزایش صدا از سطح تعیین شده ، خروجی ماژول تغییر حالت می‌دهد . از این ماژول می‌توانید در سیستم های مختلفی نظیر کنترل روشنایی از طریق صدا (مثلا با کف زدن دست یک لامپ روشن شود) استفاده کنید . ولتاژ تغذیه ماژول 3.3 تا 5 ولت است .

The Microphone module can be used for sound/audio detection, it comes with the basic
components for you to get started. Supplying power and it is good to be use. Do take note
that this sensor module can only detect the present of sound/audio, but not to differentiate
the sound’s level. You can use it to detect sound and further determine whether human or
animal is preset in a room, maybe for light activate with clap.
The is only digital output. Threshold can be adjusted with on board potentiometer for the
digital output. Simple usage as it is digital output, so you will know whether there is
sound or not.
Comes with a M3 mounting hole for ease of attaching it to any object. On board it has
microphone, high sensitivity and commonly being used for sound detection. The module
comes with power LED and status LED as indicator.
It can be interface with any microcontroller with digital input such as PIC, SK40C,
SK28A, SKds40A, Arduino series for sound detection. Also, not to forget, interface with
Relay module offer sound switch 🙂
Features:
 Operating voltage: 3.3 to 5VDC
 PIN: VCC = 5V, GND = 0V, DO = digital output from module
 Sound detected, DO = LOW, on board LED is ON
 No Sound detected, DO = HIGH, on board LED is OFF
 Turn the on board potentiometer clockwise will make module sensitive to sound
 Turn the on board potentiometer counter clockwise make the module less sensitive to sound
