Water level indicator cum controller

Water level indicator cum controller

Wednesday, 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.

1. Switch 1 is the main power switch which is used to activate the system.2. Switch 2 is used to select whether to operate the pump in AUTO or MANUAL mode.3. 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:

http://electrofriends.com/wp-content/uploads/2008/11/circuit1.gif

There are two modes of working for the system

1. Manual mode2. 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.

hi..i need d firmware n other details of this project..im Third yr student.

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

HiI 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 3For “dry run protector”, there should be a condition in the program such that motor should stop when water touches to probe “E” of tank200 amps relay is sufficient for 1 hp jet pump.

39. Sadish Shrestha 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.
