How do I use a sound sensor module Arduino?
First you need to supply power to the sensor and the relay module. Connect their VCC pins to the 5V pin on the Arduino and GND to ground. Next connect the output pin (OUT) on the sound sensor to the digital pin #7 on your Arduino, and control pin (IN) on the relay module to the digital pin #8.
What is Arduino sound sensor?
Arduino Sound Detection Sensor. This module allows you to detect when sound has exceeded a set point you select. Sound is detected via a microphone and fed into an LM393 op amp. The sound level set point is adjusted via an on board potentiometer.
What is microphone sensor?
A microphone is a sensor or transducer which converts sound to electric signals. When the moving plate (diaphragm) vibrates in time with the sound wave, the distance between the plates and hence the capacitance is changed. The changes in capacitance can then be converted to an electrical signal.
What is microphone sound sensor?
A sound sensor is defined as a module that detects sound waves through its intensity and converting it to electrical signals. sound sensor consists of an in-built capacitive microphone, peak detector and an amplifier (LM386, LM393, etc.) that’s highly sensitive to sound.
What is Arduino microphone?
The microphone requires low power and can be powered directly on the 5V pin of the Arduino. It returns an analogue value which will be sent to an analogue input of the microcontroller. Depending on the model used, a potentiometer is present on the module to adjust the microphone sensitivity.
How do microphone sensors work?
A microphone is an acoustic to electric transducer or sensor that detects sound signals and converts them into an electrical signal. Vibration of the diaphragm causes surrounding components of the microphone to vibrate. Conversion of these vibrations is delivered as an audible signal.

What is a microphone sound sensor in Arduino?
The microphone sound sensor, as the name says, detects sound. It gives a measurement of how loud a sound is. There are a wide variety of these sensors. In the figure below you can see the most common used with the Arduino. At the leftmost side, you can see the KY-038 and at the right the LM393 microphone sound sensor.
What kind of sensors are used with Arduino?
There are a wide variety of these sensors. In the figure below you can see the most common used with the Arduino. At the leftmost side, you can see the KY-038 and at the right the LM393 microphone sound sensor. Both sensor modules have a built-in potentiometer to adjust the sensitivity of the digital output pin.
In this example, a microphone sensor will detect the sound intensity of your surroundings and will light up an LED if the sound intensity is above a certain threshold. For this example you’ll need the following components:
What is ky-038 microphone sensor?
Microphone Sound Sensor, Digital Output only KY-038. Microphone Sound Sensor, digital and Analogue output KY-039. Pulse Rate Detector, high sensitivity so shield from mains lighting
