Which sensor should I use to measure the volume?

Where am I?

Hi Philippe,

if you want to detect a sentence, you need iot and VPN to work with google assistant, cortana or alexa. You can find a nice exercise like that in the video below.

If you just want to measure the volume, go ahead and connect a microphone directly to the tokymaker input. Make sure that the microphone can work with 3.7v. 

Here is a link to a shop that sells these kind of sensors:
