When the water level reaches to Point A in the tank, the positive side of the battery gets connected to the base of the Transistor Q1 through the water. Basically ultrasonic sensor have two openings one is transmitter and other is receiver. The Echo opening receives the Echo waves. We can use the logic of making an automatic light detector to make a simple. The sensing is done by using a set of nine probes which are placed at nine different levels on the tank walls with probe 9 to probe 1 placed in increasing order of height, common probe i.
The other wire receives the current from the probe dipped in the water. The water level indicator is defined as a system which gets the information about the water level in reservoirs or in tanks which is used in homes. Insulation of wires is to be removed from the points shown. I reduced the value of R1 to 330 ohms as suggested by Sri Seetharaman Oct. The circuit presented below surmounts this flaw and displays the water level using seven segment display, but there is a difference. We can find water level indicators are made by 5th grade students for science fair at school. Regards, -Rams I am not having much knowledge about electronics.
S: I am using an aluminium wire dipped in the water. In order to avoid the scratching of the bathtub, the magnet can be covered with plastic or rubber. Your circuit seems to be really simple with minimum components. Nowadays everybody has overhead tank at their homes. Water Level Indicator Using Arduino Ultrasonic sensor has two openings, one is Trigger and the other is Echo.
If it is filled ,itshould start Pump No. We are providing complete information i. Now put the loops of wire to the nuts that you have snuggled to the plastic wire biting and make the wires come out from every nut that you have built. Therefore, R4 will be connected across the full supply voltage and the remote circuit will draw a current of about 9mA. Basically Arduino gives the command to ultrasonic sensor and wait for response, when response is received it calculate the time and convert it to distance, further this distance is changed into water level.
After years of research and by trial and error, I found one and wanted to put whatever I have done out here so that it may be helpful to someone who has a overhead water tank at their homes. He successfully built the water level indicator circuit provided in the present article. There are two sources of water supply: a Ground level storage tank being filled by public Utility Supply. In small electronic shops they mention only the resistance value. Check out the circuit too! Worth mentioning I am just beginner and a hobbyist hence followed every thing verbatim.
The source code of this article is available on www. This output is given to the buzzer. As in figure this is the tank that we are going to install the sensor. If you can spare the time answer me in regular email please. Dear sir, I am very much interested in your Water level indicator and preparing to assemble one soon. Enclose the circuit board along with the 9volt battery, allowing only the output wires terminating towards the stick. On the other side of the tank, Sensors ie.
If possible I would also like to auto fill the 64oz container. The sound waves hit the water and are reflected back in the form of Echo waves. Tel no: 00966-530279520 Email: Kingdom of Saudi Arabia Jeddah City. As for the next step, can you kindly let me know from where I can get the stainless steel rods as these are not so commonly available in the market. This is shown in the figure. So we can easily measure the level of water, it will be difference of height of tank and distance measured by the sensor.
The transistor is biased by a 470K resistor with the ground and the sensing part is taken from the collector with a 33 ohms resistor going directly to the tank. Also i will like to know to try out my prototype on a breadboard. Therefore after the wire is connected to the connector. The operation of this project is very simple and can be understood easily. In case Roof-top tank goes dry and ground level tank is also empty, the circuit should wait for 2 minutes and then start Pump No. The battery will last very long because the circuit will be mostly in the off state. For example you can measure the whole length and divide it by seven, as because you have to mark seven different points for sensing seven different water level.
Battery should be around 3. When tanks gets filled completely we get beep sound from Buzzer. Now measure the height of water holding capacity of tank as shown in the above image and write in down in meters. Dear Sir, Very interesting project and it is working fine … i have request on this program. This is often needed because the conductivity of water changes slightly from place to place.
