Title: Amplifier for using piezo knock sensor as microphone
Post by: rvalente on April 16, 2021, 09:19:07 pm
Hello mates,

I'd like to make a small amplifier to use a automotive knock sensor as microphone and trigger my timing light (to check correct timing of diesel engines)

What kind of amplifier should i use? Inverted single ended? Differential? Instrumentation? I've not found much literature about it..

Attached a bosch knock sensor datasheet.

greetings
