Hi folks, as per title, I Need peak value of 2 microsec voltage spikes occurring every 1.67 seconds. The main point here is that I only need the peak values and so I am trying to avoid high Sample rate data collection… High rate ADCs etc.
What springs to my mind is some sort of capacitor whereby the voltage spikes push the capacitor after maximum level ( The peak voltage) and then reset based on the low voltage noise or perhaps a on a time basis.
The attached is a diagram of what I need. In the diagram, the capacitor is analogous to a system you could set up in the ocean waves to measure peak wave heights whereby a float and sits in a tube sitting in the water vertically. When the wave passes, By virtue of some sort of ratchet system, the float can only move upwards. Hence, the float would stop moving upwards when the peak wave height has passed and would reset between waves.
Equipment I currently have is
A nodeMCU ESP8266
A teensy 3.5
Both running on windows 10 with Arduino IDE 1.8.9
Any bright ideas re finding the right capacitor and hooking into ideally the nodeMCU? Is a capacitor the best tool for the job?View attachment 16535
Cheers, Nick
