Sound Sensor dB range

Hi everyone, I’m thinking to buy the Grove - Sound Sensor (<LINK_TEXT text=“https://www.seeedstudio.com/Grove-Sound … p-752.html”>https://www.seeedstudio.com/Grove-Sound-Sensor-p-752.html</LINK_TEXT>).

What is the range of this sensor in dB? I need a sensor that is able to go like 80dB / 90dB maximum range (or more). Thank you for the help!

Hello,

This grove is designed for voice control, but not measurement. And the output of the example code is a relative value. So if you want to use it to measure accurate volume, you need to establish the mathematical model and calculate the range by yourself.
