Hi @ROnod.1​ ,

Please check first if the translation is correct:

I want to connect a piezo element pressure sensor to STEVAL-BCN002V1B and get the value, but it doesn't respond.

I am using a sample application customized with IAR. The app uses an android sample app. Please let me know what to watch out for.

If so, how did you connect (at hardware level) the piezo element with the STEVAL-BCN002V1B? Usually, a (bare) piezo sensor needs quite high voltages to work, and this cannot be generated by the motherboard...

Best regards,

Eleon

Hi @ROnod.1​ ,

I'm not an expert of this force sensor, but I agree with you that you might need an additional circuitry to make it working, properly managing the supply (e.g. 5V if compatible with the BlueTile) and the output, as described in the datasheet.
