How does the Arduino sound sensor work?
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. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low.
How do you adjust a sound sensor?
On the top of the sound sensor is a little flathead screw you can turn to adjust the sensitivity and analog output of the sound sensor. To calibrate the sound sensor you can make some noise and keep turning it until you start seeing the sensor-LED on the module starts blinking with the rhythm.
Where can a sound sensor be used?
What is a sound sensor used for? Applications
- Consumer electronics such as phones, computers, music systems.
- Security and Monitoring systems such as burglar alarms, door alarm, etc.
- Home automation such as lighting your house by detecting whistle/clap instead of physically turning the light switch.

How does a sound sensor work on an Android phone?
This sensor is capable to determine noise levels within DB’s or decibels at 3 kHz 6 kHz frequencies approximately wherever the human ear is sensitive. In smartphones, there is an android application namely decibel meter used to measure the sound level. This sensor includes three pins which include the following.
