this is my first post ever on arduino so please be nice lol.
i am working on a project where i need to read wind speed of a tube, so i am thinking about using an automotive MAF Sensor to do this job since its proven to be durable enough to be used in cars.
from my understanding, the MAF sensors requires a 12V to power it, and it gives a 0-5V output signal according to the wind speed.
i want to use the MAF sensor ALONE, without connecting to any car ECU.
these are my questions －
- how do i wire the sensor, as in which pins should i provide what kinda power (5 or 12V)?
- which pin can provide me useful infomation/signal (i'm guessing 0-5v output)?
thanks in advance
