Hello to everyone. My appologies if this question has been here answered, link to discussion would be nice.
I am in process of designing my own board based on pazi work and others.. I am developing a board with enclosure and 2x24pin plugs off aliexpress, generaly used in LPG applications.. 4cylinder sequential injection and ignition using mega 2560pro board...
Anyway, back to the topic.
I am wondering, what is correct way to design sensor ground ? I mean, does it is thesame as power ground, or is it seperated or connected like with a shunt resistor or something? Is there any filtering inbetween those two grounds on the board ?
I do understand that sensors must have a good ground connection in order to get correct reading of the sensors.
