| Sound Sensor |
Description:
The sound sensor module provides an easy way to detect sound and is generally
used for detecting sound intensity. This module can be used for security, switch, and
monitoring applications. Its accuracy can be easily adjusted for the convenience of
usage.
It uses a microphone which supplies the input to an amplifier, peak detector and
buffer. When the sensor detects a sound, it processes an output signal voltage which is
sent to a microcontroller then performs necessary processing.
The sound sensor has a built-in capacitive electret microphone which is highly sensitive to sound. Sound waves cause the thin film of the electret to vibrate and then the capacitance changes, thus producing the corresponding changed voltage. Since the voltage change is extremely weak, it needs to be amplified. So it is converted into a voltage ranging from 0 to 5V, which is received by data acquisition unit after A/D adapter conversion and then sent to an MCU.
Specifications:
- Operating voltage 3.3V-5V
- Output model: digital switch outputs (0 and 1, high or low level)
- With a mounting screw hole
- PCB size: 3.4cm * 1.6cm

How to test:
The components to be used are:
2. After hardware connection, insert the sample sketch into the Arduino IDE.
3. Using a USB cable, connect the ports from the Arduino the computer.
4. Upload the program.
5. See the results in the Video below.
The components to be used are:
- Arduino UNO
- Sound sensor module
- LED
- Breadboard
- USB cable
1. Connect the components based on the figure shown in the wiring diagram using
a M-M pin connector. VCC pin is connected to the 3.3V or 5V power supply,
GND pin is connected to the GND, DO pin is connected to a digital I/O pin (pin 3 ). Pin number will be based on the actual
program code.
2. After hardware connection, insert the sample sketch into the Arduino IDE.
3. Using a USB cable, connect the ports from the Arduino the computer.
4. Upload the program.
5. See the results in the Video below.
