Water level alarm circuit June - 26 - 2008 36 Comments
Description. Here is a simple water level alarm circuit that will produce an audible alarm when the water level reaches a preset level.The circuit can be powered of a 3V battery and is very handy to use. The circuit is based on an astable multivibrator wired around IC1 (NE 555).The operating frequency of the astable multivibrator here will depend on capacitor C1, resistances R1,R2 and the resistance across the probes A&B.When there is no water up to the probes,they will be open and so the multivibrator will not produce oscillations and the buzzer will not beep.When there is water up to the level of probes,some current will through the water,the circuit will be closed to some extend,and the IC will start producing oscillations in a frequency proportional to the value of C1,R1,R2 and the resistance of water across the probes.The buzzer will beep to indicate the presence of water up to the level of the sensing probes. Circuit diagram with Parts list.

Notes. The circuit can be powered of a 3V battery. Assemble the circuit on a good quality PCB or common board. The probes can be made of two insulated copper Aluminiun wires. Place the probes at the position where you have to sense the level.

Mandar says: June 9, 2011 at 7:53 am @ Deepesh Shah Connect a 0.01uF capacitor between pin 5 and ground (-ve of the battery ) jesmin patel says: May 17, 2011 at 9:54 pm mail me any latest news or innovation on circuit Deepesh Shah says: May 16, 2011 at 9:47 pm In this circuit where pin no.5 is not shown. So to run the circuit where it should be connected. Kamaljit Singh says: May 10, 2011 at 8:50 pm Hi Seetharaman, yr Idea has been of great help for 15 days. Now the ends of the wire that I dipped in the Water tank have sulphated and do not conduct. After every 20-25 days I need to clean the ends of the wire in the water tank. Pls suggest some other sensors which need no cleaning. Thanks Seetharaman says:

April 26, 2011 at 9:31 am Hi Hafeez pin no5 is not used and not required for this application. hafeez says: April 25, 2011 at 6:19 pm wr is pin numbr 5 in ic pls tell me i want to do it in 2hr nw Seetharaman says: February 25, 2011 at 4:54 am Hi Bijay 2.7 to 12 volt music generator modules are available you can use one of them. Bijay says: February 24, 2011 at 9:21 pm Thanks to seetharaman, the project is completed i have connect the 3-24v buzzer its not working, then to test the alarm i connect a 3v bulb in place of buzzer. i notice that the light is flashing ( is it ok flashing of bulb). can u suggest what kind of buzzer should i purchase, Seetharaman says: February 24, 2011 at 10:03 am Hi Bijay you cxan use resistance in any direction as they have no polarity like diodes and electrolytic capacitors. regarding NE555 pin connection refer following document in the out line it is shown clearly in the numbers will increase in anticlockwise direction as you view from the IC identity – screen printed / engraved side. http://www.fairchildsemi.com/ds/LM/LM555.pdf Bijay says: February 24, 2011 at 12:01 am Seetharaman thanks for the help. just now i purchased everything,, i m new to electronics, don’t have any background in electronics, just for hobbies im doing this project, pl help i m confused regarding the IC555 terminal, in diagrams it showing 1.2.3.4.5….8 how to locate the nos in IC pl help. and 1 more thing can solder resister in any direction, Regards Seetharaman says: February 23, 2011 at 11:38 pm Hi Bijay normal mobile chargers voltage lies between 5 to 7 volt can be directly used as the IC can operate up to 15 volts. Bijay Singh says: February 23, 2011 at 8:44 pm hi all. instead of 3v batteries, i would like use transformer of 3volts. pl let me know how to built that 3volt AC-to DC, can i use mobile phone charger for that.. vara ELURU says: December 7, 2010 at 4:08 am Hiiiiiiiiiiiiii friends this ckt is working try this Yohoho says: November 25, 2010 at 10:22 am Where is the parts list Seetharaman says:

November 4, 2010 at 1:44 am Hi Neenoo it is 3volt DC. you can use a single lithium battery 123 or 2nos 1.5 volt cells in series. i think ac batteries are yet to be invented. NEENOO says: November 3, 2010 at 10:34 am ia it an AC BATTERY OF 3V OR A DC BATTERY? Edwin Raj says: September 17, 2010 at 7:32 am it helped our student to get some ideas for the science exhibition that is taking place in our school…. thanks a lot…. please mail me/… pawan says: August 13, 2010 at 1:01 pm sir i need a simple circuit daigram for my science project please help me within 15 aug please reply on my mail immidiately anyone please seetharaman says: July 14, 2010 at 8:28 am Hi Patrick you can use 5amp house wiring wire 2 runs(1/18wire). You can use 5 volt power pack, which is standard these days for charging mobile phones. patrick vaz says: July 12, 2010 at 6:26 pm The tank at my place is located at 60ft above. I live at ground level.I want to connect 2 copper wires from ground to tank. but can 3 volts battery be replaced with electrical power circuit. Thanks Narendra says: April 7, 2010 at 9:01 pm if you are not able to hear the buzzer sound, then put only the sensors in the tank and connect it with rest of the circuit via the pipes which bring water to your home ,if they are made up of metal. sahitya says: February 9, 2010 at 7:53 am please give the parts related information and their cost phani raj says: February 7, 2010 at 11:24 pm how to make this suitable for multi level indicating . . naresh says: October 13, 2009 at 6:32 am give information on Water level alarm circuit project kandarp says: September 7, 2009 at 1:28 am which part of this ckt is sensor part?pls,reply me..thanks.. regards says: August 5, 2009 at 2:53 am

the best solution is to keep the sensor part only in the tank and rest of the circuit in some place where you can easily hear the alarm.Connect the both parts by using wires.That is what i have done. ravikumar says: August 4, 2009 at 9:27 am the circuit is working fine.but the problem is our water tank is kept at a height of 20-25 feet.the audibility of buzzer is upto 10 feet only.how can i improve the buzzer sound. please suggest me necessary changes to be made to this circuit ? avinash says: July 22, 2009 at 4:29 am mail me any latest news or innovation on circuit emmanuel says: June 5, 2009 at 10:19 am mail me any latest news or innovation on circuit emmanuel says: May 28, 2009 at 2:56 am yes o
