piezoelectronic as battery for MSP430

[tiger200099]

anyone can help me to design piezoelectronic as input element. it work with vibrations and can count everytime i get the signal and diplay it on LCD using MSP430

 

[tpetar]

Something as vibration/shock sensor ?

thank tpetar for replay, yes something as vibration/shock sensor

yes thomething as vibration or shock sensor

thanks tpetar can i use this small power to on the MSP430 and count everytime i get the siganal on LCD like in shot counter?

 

[tpetar]

You can experiment, with zener diode you can protect analog input.

thanks tpetar have to convert the input signal to digital through ADC to make my counter work and diplay the number on the LCD?

 

[tpetar]

You can use transistor to make digital signal for uC.

do you know tpetar the smallest (SMD piezo) that i can use to drive my microcontroller

 

[tpetar]

do you know tpetar the smallest (SMD piezo) that i can use to drive my microcontroller

This is small, but check if can drive uC :

Dimensions: 16 x 16 x 2.6mm


Dimensions: 14.3 x 14.3 x 8mm

is this piezo you did send word with the vibrations?

do you know tpetar i am looking for pizo that work with the vibration

 

[tpetar]

All piezo are sensitive to vibration some more some less. By my thinking, bigger surface area in contact with vibrations will give better results. This request experimenting, remove piezo elements from older dialup modems, chinese sound greeting card, ... and do various experimenting. Theory and theories are just as dream, practical experiment is reality.
