hi, we are trying to put a pressure sensor on our air suspension system.. we are using arduino and 8 channel relay.
the problem is that when the valve is on to get air from tank. we get a high spike of pressure and we dont get the accurate reading.
can anyone help me with this or any idea what to do?
we already tried putting else where the sensor. but still same result.
thank you
Remember, you are working with a fluid. It has inertia, meaning it can't magically move from one place to another instantly. If you want a steady pressure, then you have to open the valve very slowly to give the gas time to fill the air suspension system.
So, I guess, if you are using a solenoid valve to allow high pressure air into a lower pressure system, you have to expect just what you are seeing.
