Help for project

Hello,

I doing a project for school and I wanted to make sure the items I’m buying will able to work together.

I have two pmods:

And a piezo sensor:

Will the piezo sensor be able to work with both of them?

Thank you.

@johnsan1,

Do you have another device, of which is not listed above? The piezo sensor you listed must be driven by something, your two other devices are a wifi interface and a sensor (thermocouple). You’d need something to drive these 3 devices.

Regards,

Yes, I am also using a nexys a7: fpga trainer board.

The ADC’s on that board can not handle signals from that sensor without some form of signal conditioning…

Take a look at this article:

Regards,

Ok so a few questions.

How would you interface the op amps to this project? Also once I am able to connect the op amp to the piezo sensor, everything else should work fine right?

Thank you so much for helping me.

@johnsan1, if you don’t want to design your own circuit, I believe you could use this pmod adapter:
