Water level indicator cum controller
by Ranjith | November 19th, 2008.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.
Front view of the model
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.
Circuit diagram of Water level indicator cum controller
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

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.
January 18th, 2009 at 12:53 pm
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.

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.
