The present concept implements controlling of pump which pumps water from the sump (underground tank) to the overhead tank, using 8951 microcontroller.
The control panel, i.e. the main control unit of the system which consists of the primary control switches, pump indicator, siren and level indicators. The visual example of how switches And the indicators can be placed as shown the figure below.
In the figure shown above there are total of nine LEDs, four of which indicates the water level in the tank, another four indicates the water level in the sump and one LED indicates whether the pump is ON/OFF. It also consists of three switches.
- Switch 1 is the main power switch which is used to activate the system.
- Switch 2 is used to select whether to operate the pump in AUTO or MANUAL mode.
- Switch 3 comes to picture only when the system is operated in MANUAL mode. It controls the direct activation of the pump.
Description :
This system is built around an 8951 microcontroller and the circuit diagram is as given below.
As you can see in the above diagram, port 0 is exclusively used as an input port which takes the information regarding the water level in the sump as well as in the overhead tank.
Port 1 is used as output port which is connected to the indicator that indicates the water level in both the tanks.
Port 2 is used as in/out port, it takes the input from switch 2 and switch 3 and gives the output which is connected to pump indicator, siren and the relay which controls the switching of the pump.
Working of the system:
There are two modes of working for the system
- Manual mode
- Auto mode
Which is controlled by switch 2 (refer control panel diagram)
Manual mode:
When the system is active and in manual mode, it only indicates the water levels in the tanks and it doesn’t control any working of the pump. To activate the pump in manual mode switch 3 is used.
In this mode the operator should manually control the working of the pump. As in case if the tank is full, operator should switch of the pump which is not the case when compared to auto mode.
Auto mode:
When the system is active and in auto mode, it only indicates the water levels in the tanks and it controls the working of the pump.
Hi, I am Arindam .I have some question about this water level controller.
1. I cant find any firmware for 8951 chip.
2. can you add a LCD Or Seven segment display for status(HALF, FULL, EMPTY).
3. can you add motor dry run protector means when water not flow to overhead tank, motor must turned off.
4. amps rating of relay for 1 hp jet pump.
I have only overhead tank and 1 HP motor , so can you help me to implement this project for my case with above mentioned features.
I will be highly obliged if you spread your helping hand in this regard.

sir i require the firmware and hex code for the water level controller project
please help me in this matter
1.can you add a LCD Or Seven segment display for status(HALF, FULL, EMPTY).
2 please can i have an analysis of special function registers in 8951 microcontroller
sir,
i am b.tech student and iam doing water level project so i need program of this project.
hi..i need d firmware n other details of this project..
im Third yr student.
Hi
I have given this project idea to help students to do project their own.
Here LCD or Seven segment display can be used for status using port 1 and 3
For “dry run protector”, there should be a condition in the program such that motor should stop when water touches to probe “E” of tank
200 amps relay is sufficient for 1 hp jet pump.
i m kamalpreet , plese send the assembly language progamme and also the hex file for this project.
sir,
im doing my 8th sem project on water level indicator cum controller, iam trying to write the code can you please give the program for this.
sir i require the firmware and hex code for the water level controller project,plese send the assembly language progamme and also the hex file for this project,and other details of this project.
sir i have require the firmware and hex code for the water level project.
please send it to me.
The project is very helpful. I need the code for the water level controller. Please help me out.
pls provide me the firmware and hex code…..needed urgently
plz provide me the program n hex code for the same…
hello…i dont hav much time to make this project..
or i shd say icant make it. lol.
no idea
so ..can ne1 gonna tell me..how much it wil cost?
if i jus buy it frm outside..
or if any one know place where i can get a cheap.do tell me..plz.

sir.please provide me with the assembly language code or the c language code of the water level indicator.
needed urgently.
dear sir,I want firmwire of 8951 and hexcode for the water level controller and the process to burn.
Sir, I need an assembly language program for the same, pls help me .
The projaect is very good excellent but I need the hex code of the Water level indicator cum controller. Without hex code the circuit is useless. Please, can you send to the hex code to my mail adderess.
I,m Providing u with d code,change it according 2 ur convenience.

solangi01@gmail.com
sir pl sent mail ofsource code.dvsphani@gmail.com
any body can u send water level cum motor protector block diagram
microcontroller is new to me…so my doubt may be a simple one..but i dont know thats why i am asking….
Where to connect a motor ?
& please telll me the function at P2.4…i am not getting it by reading…
the probes you are using for sensing are they copper probes ?
i need code in c language for water level cum controller please help me……
hi
can u give me the souce code for waterlevel indicator cum controller in c language….
Hi, i need a pressure measurement and controller circuit diagram and c program code using 8051 micro controller.
please can you send the complete diagram of the water level monitor showing how the lcd is connected. i also need the firmware and the source code necessary to make the project perform to it’s expectation. thanks for your support. my mail is olaibilade@yahoo.com.
can i get configured 8951IC and pcb lay out?
hey can i get the hex code file & pcb layout for this water level project.mail me soon. thnx
Hello Sir,
With your design I have made my own water level controller with different code. The project runs good when kept outside water by touching the probes. By when keeping the probes in water it works for sometime and fluctuates making the motor on and off within some seconds. I dont think there is any problem with the hardware and software but with the probes. Suggest we a suitable and cheap probe yo be used.
hey can u pls xplain the xact working of the exp as in the uses of relay n the other components frm viva pt of view.
thanx
CAN ANYBODY SEND ME THE ENTITRE WORKING AND BLOCK DIAGRAM OF THIS PROJECT..THANK UUU
