Loudness Sensor to Decibel

#1

Hello there,



Does anyone know how to convert the value (0-1023) out of the Loudness Sensor http://wiki.seeedstudio.com/Grove-Loudness_Sensor/ to Decibels?



I’m using a Raspberry Pi Zero and the GrovePi Zero kit



Thanks in advance.

Hi there:

At the beginning of the design, it was only used to test and simulate an analog number, and whether it was converted to decibel, so it did not support it.

So there is no way to get a correct db value out of the 1024 values?

Dear Costumer:

The loudness sensor was originally designed not to test decibels。If you want to get the decibels,you need to calibrate according to the application environment，this will be difficult and very troublesome.
