Water Level Monitor Using pressure sensor & 15led’s Arduino bar-graph display

Project name “Water level monitor using pressure sensor”

I have tested this project with Arduino 15 LED’s Bar-Graph monitor and MPXV5010DP sensor, sensor included inbuilt signal conditioning circuit, output is sufficient to drive the ADC of Arduino, I have used A1 analog pin as input. Water level is around 9 Inch. Operating voltage of this circuit 5V DC.
