What is sound sensor?
The Sound Sensor is a small board that combines a microphone and some processing circuitry. It provides not only an audio output, but also a binary indication of the presence of sound, and an analog representation of its amplitude. It is a simple microphone. Based on the power amplifier LM386 and the electric microphone, it can be used to detect the sound strength of the environment. The value of output can be adjusted by the potentiometer.
WORKING PRINCIPLE OF SOUND SENSOR :
USES OF THE SENSOR:
Operating Voltage – 5v / 3.3V
Can detect sound/noise etc
Sensing element is a condenser microphone
Has an ON BOARD amplifier and gain adjustment
- Sound Detector Module
- Arduino UNO
- Jumper wires
Connection with Arduino:
|VCC||5 Vdc from your Arduino|
|Ground||GND from your Arduino|
|Out||Connect to Digital Input Pin|
|Power LED||Illuminates when power is applied|
|Sound Detection LED||Illuminates when sound is detected|
|Sound Set Point Adjust||CW = More Sensitive
CCW = Less Sensitive
- Use of sound sensor in a home security system.
- Use of sound sensor for making an amusing toy.
