Water level indicator cum controller
Wednesday, November 19th, 2008The 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.

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.
January 20th, 2009 at 2:52 pm
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.

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 ?

hey can i get the hex code file & pcb layout for this water level project.mail me soon. thnx
October 9th, 2009 at 7:05 am
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.
October 21st, 2009 at 10:43 pm
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.

Hi…
Thanks for this project… Its really a great one…
Pls can you hlp me with this one:
Remote industrial Monitoring of tank WAter Level, Converyor belt speed, using an 8951 microcontroller?
It should be interfaced to a computer via parallel or serial port… I hav already worked on interfacing the transducers via current sense amplifier and adc to the microcontroller… I just need a working connection, an Assembly language code, and a monitoring software (I intend using matlab 7.0 interface).
Thanks…

i wanna do this project in arm7tdmi
can anyone send me the code for the same???
March 6th, 2010 at 7:41 pm
there is a design fault..
you must provide an isolation between the uc ant he relay.. els the program will get flashed out..
recoment a optocoupler(pref. MCT2E) for isolation…

hello plz send the hex code 4 this project as soon as possible……project is good….
August 21st, 2011 at 6:30 pm
sir,
i am having the doubt ie,since the input from the tank is analog how it can sense by the 8951.i am having similar project but i stukked with the problem of giving input to ic.can you say how we can give input to micro controller
to drive the motor if input is on.
yours faithfully
ansar ah

sir,
i am having the doubt ie,since the input from the tank is analog how it can sense by the 8951.i am having similar project but i stukked with the problem of giving input to ic.can you say how we can give input to micro controller
to drive the motor if input is on.
yours faithfully

Hi,
I want to use this circuit with my tube well, ie., the over head tank and the circuit, as and when water in the over head tank falls below the E level the pump starts.
Regards

sir,
i last year student and need do my final year project, so i need to develop 5 water level..but i don’t know how to built it. it new for me to use micro-controller..can you send me the source code for micro controller based water level controller using PIC 16F877A. n i also need any related circuit diagram n flow chart for this project.
thank sir,
u can email me at

sir,
i want to make this project for industry purpose. and that also should contolled by remote. how can i do this?plz guide me.
January 8th, 2012 at 10:38 pm
sir,
i am a computer scince student but i do the water level controller prjoect.so please send some link for that project to my mail sir.
thank u

its a nice one , but i think this can be only by using a uln ic , here is the idea, u can replace the buzzer with a relay to control the pump or use both or just leave it as it is http://teeblog.blog.com/archives/790/
