Sound Level and Intensity Meter using Sound Sensor & Arduino

In this video, we have interfaced the Arduino sound module with Arduino and 16*2 LCD for designing a simple decibel meter for measuring the sound level and intensity. The module is capable of measuring the sound intensity and loudness levels. The programming is done on the basis that whenever the sound is not detected, it displays sound level as zero value. The value of sound level ranges from 0 to 1000 or more. low-level intensity is considered as 0-50, medium as 0-500, and high as above 500. On a high level, the red LED glows indicating the sound is too high.

Im just wondering where u connect the led to the bread board?

[rakeshakash]

can u please share me the labview project on this sound level meter concept

[alalariq]

what type of sound sensor are you using?

[madha]

hi for the sound module is it possible to use it with raspberry pi?

[MXbR]

Which is the formula for calibration?
Which parameters i need to change to show better ranges?

[urgayll]

hi, i have just tried out this circuit. im having trouble with the sound level. i believe i connected it correctly but the LCD sound level stays at the 200 range. i followed your instruction on the website

Hi! I'm trying to try this project.
Could you explain where to put LED light on the bread board??

Hi. Could anybody please post a build of Arduino decibel meter for an Airgun with shown Max last reading. Small size would be preferable, possibly Arduino Nano and Oled screen. Most Android Phone Apps don't work correctly as the phone kills the Microphone sensitivity automatically and sampling isn't fast enough. Thanks in advance. Good Video BTW.
