The Sound sensor module is a simple microphone. Based on the power amplifier LM386 and the electret microphone, it can be used to detect the sound strength of the environment. The value of output can be adjusted by the potentiometer.

Grove - Sound Sensor
This wiki is for Grove - Sound Sensor
I would like to use this to send audio frequencies to an Arduino Uno board for light up the 3 different group of RGB LED. The single Led is on by one frequencies of sound (low, medium or high).
how much sensor i need, one for single led or just oneQuestion by: admin on 2018-12-18 02:39:15
It can detect the sound strength of the environment, but not the audio frequencies. If you wanna use one to judge the level of sound, yes you can.Answer by: admin on 2018-12-18 02:39:15
I would like to use this sensor to detect pure tones and to react Arduino depending of each single pure tone sent. So, can it be used in this way?? Any demo code for this one?Question by: admin on 2018-12-18 02:39:15
Hi there, it can only be used to detect the sound strength of the environment. About the demo code you can go to Wiki Page to view and refer to.Answer by: admin on 2018-12-18 02:39:15

Hi, Can you support the formula to calculate the corresponding db value of output analog voltage? Thanks.Answer by: admin on 2018-12-18 02:23:26
Question by: admin on 2018-12-18 02:21:17
Thank you, I know that the sensor will not be able to record directional information. I was wondering what in what directional pattern it picked up sound such as: omnidirectional, cardioid, or bidirectional. This would provide information as to which direction the sound has to be coming from for the sensor to pick it up.Answer by: admin on 2018-12-18 02:21:17
