You should try to find a data sheet for the sensor you are using. There should be some information about the connection included with the sensor. If not, contact the supplier you got it from.

The Arduino .ino file contains quite a bit of documentation including a link:
https://github.com/MikeOchtman/Pi_Arduin...ev%202.pdf

This has a detailed description of the connection between the Pi and Arduino.

The idea is that the pressure sensor is connected to the Arduino not the Raspi. The Arduino has an ADC for converting analog sensor data to digital which The Pi can use. The Arduino can be at a distance from the Pi so that the Pi does not need to be located where the pressure senrsor is.

DAN,

Can we not use water flow sensors instead of water pressure sensors or transducers because water flow sensors are easily available. Rest everything will be the same. I dont know how to roll plugin? Can you help me with that? We can use water flow sensors and achieve the same.
