Question about the Grove Vibration Sensor

#1

Hello i have a question about the Grove-Piezo Vibration Sensor.



I bought it the other day, because i wanted to messure small vibrations. I found out that the example code on wiki is only giving me values of 15 or 1000 for high and low. I really have to bend it hard in order to get a 1000… I did some research in the forum too, but didnt find any solution.

Since its says in the description “Grove-Piezo Vibration Sensor is suitable for measurements of flexibility, vibration, impact and touch” i was wondering how i would get it to work, so it will notice a touch or a slight impact.





Thanks for help.

Best regards



Ole
