I have found that with the given values of the R and C, the range of this timer is between 1 - 30 mins. However, 0.22Mfd did not make any problem when the power was fed from Not allowing the oscillation to begin when the circuit was drawing power from the Added 22Mfd capacitor between pin 12 and 16 instead of 0.22Mfd because 0.22Mfd was

#Use tank circuit as timer full

Used four diodes for full wave rectification instead of just a single diode forģ. The LED starts to blink after 20 secs of powering the timer onĢ. Connected an LED to pin 7 in order to get a visual indication of the oscillation.

There were only three modifications I made:ġ. Here's the feedback email that he sent to me explaining everything regarding the working of the circuit:įinally I have managed to build, the model of this timer based water level controller project which is given below: The proposed water level timer/controller circuit was further modified and enhanced Mr.Raj Mukherji, who is also an avid reader of this blog, and a keen electronic enthusiast. Pictures of the completed water level timer controller prototype, sent by Mr. I will definitely share with you the picture of the completed project. I think this is sufficient for my purpose and also for any kind of small pumps/loads. So, I have purchased a 12 volt SPST relay which has a contact current tolerence of ~7 Amps. For my purpose, I am intending to use this timer on an AC 50 Hz, 220 - 240 volts, Crompton Greaves self priming mono-set pump, type - Miniwin II, 0.37 Kwatt/0.50 HP. So far, I was looking at the above comments and would like to add something regarding the question raised by Mr. I am planning this weekend to house it in a 4圆 box and test it on actual load. I have made the prototype on a general purpose PCB and so far found it to work accurately for my purpose: 5 min, 10 min and 15 min delay respectively (with the P1 set at 15.4 Kohms for 5 min delay etc). Thank you very much for the timer circuit. Let's learn more about his experience with the circuit. The above automatic water level controller with timer circuit was also built and appreciated by Mr.Raj Mukherji, one of my friends and a keen follower of this blog.

Relay = 12V/SPDT/contact current as per motor specification.

C2 = 1uF/25V non polar, any type will do.

The relay contacts reverts to its original state switching OFF the motor as well as the the entire circuit, halting the motor pump and hopefully inhibits the tank from overflowing. Once the timer counting finishes, pin #3 becomes high, T1 conducts and switches OFF T2 and the relay.

The above operation also simultaneously switches ON the pump motor which starts pushing water in the tank. Now the circuit holds ON even after the push button is released, everything happens within half a second. This instantly triggers the transistor and also the relay which takes over and latches ON the circuit. This momentarily switches ON the transformer which powers the IC instantaneously. The circuit is initiated by pressing the push button SW1 when the N/O contacts of the relay are bypassed.

P1 is initially adjusted through some trial and error so that it exactly matches the filling time of the water tank which needs to be monitored. The CIRCUIT DIAGRAM of this water level timer controller circuit utilizes a single versatile IC 4060 for generating the required time delay. Designing the Proposed Water Level Controller with Timer

Please provide me the circuit for above sited problem with complete parts list and diagram.

#Use tank circuit as timer how to

I am not expert in electronics but i like to play with electronic and knows very well how to solder and always trying to do some little experiments with help of your blog. I want you to help me to design a timer circuit to automatically turn off the pump at given time. I have a problem which i think is common in every home, the problem is: I have a Water Pump (which pulls water from bore) installed at my home, when my brother switch on the water pump he always forget(u know bhulakar one:P) to switch it off back:( and water tank gets over flowed and water runs in upper portion of our house:( Ali Adnan who is one of the fans of this blog. Actually the circuit was requested to me by Mr.
