Hello all,
I would like to build my own PCB to monitor in parallel from an existing system (sensor + measuring equipment)
The sensor is supplied by the V(12V-14V typical), and the signal is a PWM.
I don't have any prior experience in electronics, but I know some basics. This is what I came up with:
Remarks:
- I will be using a 3V3 microcontroller to read the PWM from the sensor
- I think i need a faster switching time than what 4N28 can offer, but that was what I found in the LTspice library (just installed the SW this week)
- I also couldn't find a 3.3V zener diode, so I just add what I found
- Please advice on a PCB layout SW
Please give me some feedback and drive me in the right direction.
Thanks in advance!
