mpx10dp water pressure sensor with Pi

Mon Oct 26, 2015 11:52 am

Hi everyone,
i have a project that reading water pressure and displaying it. I have mpx10dp sensor, i have tried couple things to read it but i couldn't figure it out. if there any way that you know or suggestion that may help would be great.
Thank you in advance.

These are simple "Wheatstone bridge" sensors, and need something like an INA128 bridge sensor (instrumentation amplifier) to create an analog output signal, followed by a standard ADC.

Presumably you intend to connect the sensor to a Pi.

You'll need an analogue instrumentation amplifier and an analogue-to-digital converter (ADC).

The signal from the sensor is very small (which is why you need the amplifier) and the Pi doesn't have analogue input (which is why you need the ADC).
