Hi I'm new to this arduino and electronic things. But may I know why I obtained difference range of analog signal data from the sound sensors (one sound sensor from grove, another one is the black ordinary sensor) and I use esp wroom 32 for iot project. the comparison is on 10 bit (0-1023)
the grove model with 4 pins but I didnt use the nc pin, give range up to 500 .
the black up to 1023.
Also if anyone have idea or guideline for me to check on the sensitivity.
Please post links to the datasheets of those sensors. Checking sensitivity....
Connect both and read them at the same time. Compare the results.
I gave you the answer as to why the Grove does not go to 1023 in your other post.
Can't help with the black sensor without knowing exactly what you are writing about. Post a link to its data sheet, a schematic of the module or a link to where you got it. Without more information there is no way to say how it works.
