[Prashant Humbre]

I am working on this project. 

 

is project given on below link is applicable for boring water also?

is boring water conducts electricity or not?

Boring Water is not very pure. It does has some salt dissolved in it. So this must work. However you may need an amplifier to amplify the signals..

hi bro

   i am also working in water level controler project

i had complete my project successfully presently but one problem my project harware area is little large 7×4″ pcb

because i am not used any microcontrls  i hope you will help me to convert my project microcontroler

i have many ideas how to make lowcost sensers i am now using five stage water contacting senser

also working very well

 

 

  LED  WHITE FULL    MOTOR WILL BE STOP HERE

  LED  GREEN 75%

  LED   BLUE    50%                    WHEN THANK LEVEL BELOW 50% MOTOR WILL BE START ALSO CHECK VOLTAGE LOW OR HIGH  ABOU 25 SEC   WHEN MOTOR IS RUN WAIT FOR WATER FLOW 40 SEC IF NO WATER FLOW MOTOR WILL BE STOP & GIVE BUZER TONE WITH NO WATER FLOW INDICATOR BLINK

  LED   YELLOW 25%

  LED   RED      EMPTY

ALSO AUTO AND MANUL SWITCH

WAITING FOR YOUR REPLY

WITH BEST REGARDS

Hi guys, i too making project on water level controller,… with 8051- i.e., AT89S51

i have circuit diagram,even assembly language program… and i hve a small try to write c program….. anybody help me please……

here the circuit daigrm and assembly lvel progrm

Program.

MOV P2,#11111111B // initiates P2 as sensor input

MOV P0,#11111111B // initiates P2 as the output port

MOV A,#00000000B

MAIN:ACALL SMPCK // checks the level of the sump tank

MOV A,P2 // moves the current status of P2 tp A

CJNE A,#11110000B,LABEL1 // checks whether tank is full

SETB P0.1

SETB P0.2

SETB P0.3

SETB P0.4

CLR P0.0 // glows full level LED

SETB P0.5
