From the wiki - hardware requirement it's understood that we are looking for a 0v-5v square wave.
My sensor from s 98 BMW 328i m52 engine gives a clean waveform but peak voltage is only 0.75v. Part number 12141709616. as such not expecting this to work since the Arduino I'm guessing has a digital high condition of greater than 2.5v input.
Anyone using this sensor? Anyone had to amplify the signal on RPM input? Or advice for getting this right?
