STOP Water Tank Overflow using Servo!! | ESP8266 Projects | Electronics Project

[@benjaminsebastian5391]

Thank you for sharing my project 😇

[@smilykittu]

This project is ok but without knowing the level in the tank turning the motor on is not a good idea. If tank is full and you turned on switch then the purpose of the project is useless

[@techiesms]

See, in my project the water wastage problem is solved completely. Let me explain In case that water tank is completely empty, we know that it will take time to fill that completely so we can set a timer of 4 min and turn on the system. So no water wastage it this scenario Taking another case like you said, what if the water tank is 75% filled. Well here let's assume that we are not aware about the exact amount of water stored in the tank but what if we are alone in the house and we need to go to toilet urgently and are not sure weather the tank has some water or not well what we can do here is, we can set a timer of 1min so that whatever amount of water the tank has, adding more water for only 1 min won't make that overflow and secondly that person (in the toilet) will also get enough amount of water he/she needs in case the water tank was about to get empty. Again No water wastage. Hence I put different time intervals here.

daymm, (for everyone reading this comment tht was based on my project) thanks for the feature. u really added another level of simplicity to the project. if in future any kind of relay sticking or something happens to my project, im definitely gonna shift to this idea.

[@TradieTrev]

It's an interesting concept! I've actually wired up & maintained water and sewerage plants, we'd never use a solution like this, than again for your low cost application I do admire your efforts.

[@vedx]

I was waiting for this. 👍🏻 There is 1 more simple solution you can use by just buying the smart switch/plug and using Google assistant or Alexa routine to automatically turnoff it.

[@madhukeshnp]

He is not interested to open the switch board. That exposes high voltage lines.

[@techiesms]

correct

[@PiyushNikam]

First of all, it's way more costly than what I use. I use a BC547 transistor with a buzzer and electrodes to detect the overflow as shown in one of the projects in the video. It costed me just 15 ₹ to make it. (Excluding the cost of wire which I had already lying around). Yeah, in 4 months (3-4 times a year), I have to change the electrodes, but atleast it's cheap and very reliable for the next 4 months. Secondly, In your project, how to know which timer to use if we don't know the level of water in the overhead tank? It's the main drawback of the project. Suppose if the tank is 75% full and as we don't know it's level, we pressed for 50% (half the timer) then the remaining 25% water will be wasted. And that's a huge waste of water. We try to save water, and end up wasting more of it.

[@madhukeshnp]

Points to be noted. Agreed. But dipping electrode is not long lasting idea. The electrodes may get a thick coating of salts and minerals from the water and stop conducting. A float switch must do the trick. This way there are no metals coming in contact with water.

[@PiyushNikam]

@@madhukeshnp yeah, float switch can be a good option, but it has its own drawbacks. The metal contacts inside the switch itself may corrode due to the humidity inside the tank. In that case, you have to either change the complete assembly of the switch or clean its contacts, which is more of a hectic task. For me personally I don't have any problem in changing the electrodes 3 or 4 times a year. It hardly takes 15 minutes.

[@PiyushNikam]

@@techiesms okay, I understand. The first case is absolutely fine👍 But the second case is very very specific and a rare scenario. So the timer will be useful only for that specific scenario and not for everyday tank fill-up. But if we somehow manage to measure the level of water, then this will be a great project. And I for sure, know that you will make this a full proof project in upcoming days. We just need to find a reliable and low maintenance way of measuring water level. The day we find that, I'll hook this everything up into my Home Assistant.

An early congratulations for 100K subs!

[@techiesms]

Thank you 😊

[@princechauhan7437]

I have added one RO float valve in one box with small holes at bottom of it. I have added that box to the water overflow pipe of tank. Once water starts to overflow it raises the float valve and closes the circuit for the water tank full indication. For water level indication I have added one recording module with my custom recorded audio in it. I also added one small solar panel to charge the battery. It's almost 6 months and it is working fine.

[@sanctuaryjames3434]

This is a good concept. But the downside is, you cannot make it a commercial product as you will be asking too many questions from clients such as 'How much time it takes for their tank to be filled?' What if they decide to start the pump when water level is half way? I WILL SUGGEST THAT YOU MAKE A PROJECT WITH ULTRASONIC SENSOR, THE WATERPROOF TYPE WITH BLYNK, SHOWING WATER TANK LEVEL AND ALSO THAT CAN BE TRIGGERED AUTOMATICALLY WITH BLYNK AUTOMATION SETTINGS AT SOME CONDITIONS AND WITH MANUAL TRIGGER THROUGH A VIRTUAL BLYNK BUTTON. THANKS

[@tinker_tech]

Nice video, looking forward to see this project made in the new blynk app

Hi Sachin, Switching the Pump On/Off Switch using Servo Motor without touching the Internal Connection is the interesting part of this project.. 👍👍

[@noelk6990]

Not every house has the switch type connection though..

[@guatagel2454]

In the channel "Leo's bag of tricks" there is a nice solution to measure the water tank level.

[@jhansipolamarasetty8871]

Hi sir myself kesav Another idea this project works only for normal pump motors. But for Submersible pumps additional controller panel buttons needs to switch on and off. Using the same principle can you try for that panel board mounting the servo horizontally. Just a thought correct me if iam wrong. Thanks waiting for your reply Amazing and great idea for this video

[@scienceoftheuniverse9155]

Hi Sachin. Please how to convert the project you did for the blynk legacy with the TTGO sim800l to the new blynk. I tried several times with no success. Thanks indeed for your great effort.

[@bharathsagar2963]

The best solution is to use cheap ultrasound mounted at top of tank The water level can be measures in high accuracy Also we can calculate the number of lts of water present in tank I use esp32 with ultrasound sensor And have dashboard in home assistant displaying water level and lts , also I made calculation to show how much water consumed in a month

[@yabesh6742]

Pls share the photo

[@madhukeshnp]

The water droplets condense on the face of the sensor and gives wrong measurements. Have you faced such issues ?

[@MrBlackpanther87]

I spent some money and got a waterproof sr04 from Bangood 8 few months ago. Completely flawless operation eversince. I have full monitoring on app and announcement on echo and message on telegram bot when tank is full or empty. I can easily control a contractor or relay to turn on and off the pump but just avoiding too much automation so that my parents can turn and off based on notifications.

[@bharathsagar2963]

@@madhukeshnp I use JSN-SR04T sensor available in amazon , I am using for my overhead sintex tank with proper air vent ( t pipes) . There is no issues of error reading from 6 month . I use this info to control relay of my water pump . The system is working without issues.

[@nitinchowdhary9469]

Try using ultrasonic sensor and blynk . It's better, I think

[@rajeevkk901]

Hai bro can u make a video for water low level and high level announcement only ( no motor operation) using Arduino uno and TF card mini mp3 module plz? 3 wire float switch for low level and high level to be used.

[@arnabghosh5800]

I would have added a water flow sensor connected to a esp at the overflow pipe of the tank. And added a second esp at the motor control switch. And let them talk to each other via wifi. That way we won't have the hastle of setting rotary switch. Also as a failsafe i might add a second flow sensor at the output of pump. So that i can precisely track how much water has gone to the tank and turn off the pump if it exceeds the tank capacity

[@satishckumar]

Hi, Thanks for the video. The idea is good, the making and alignment is a bit critical. Can you please make this 1. by utilizing ESP now; one MCU transmits the overflow signal and the other acting on this signal. In fact I was planning to add a ready made smart switch near the switch, connecting parallel to the manual switch. Then we can have manual, auto, timer, voice control options. your suggestion is appreciated.

[@noelk6990]

No

Hello which type of potentiometer r u used for this project....name it pls

[@KundanRaha]

How do I know the amount of water left in tank? In your project there is no option to check water level,so without knowing how can I set time delay to turn OFF the pump motor? It may overflow or not fully filled the tank.

[@aurobindo1231]

Just one flaw in this you will know when the water will empty and lot of time water just end in mid shower or some washing activity which is huge headache for me.....but in case of sensors I don't have to pay any attention to it as it just works and water never finished

[@mohammedkhalifa5822]

I am also facing same problem and also came up with same solution but one problem i am facing is that i have a push button to turn on the motor along with the switch so first i have to switch on the motor and then i have to push the button to turn on motor

[@techiesms]

But my project solves that as well, you just need to press the pushbutton of the project and it will automatically turn on the motor

[@vipinvg2048]

RF ransmitter, RF receiver and a floating switch . RF ransmitter switch is connected to the floating switch once it's got signal it transmits the signal to the receiver. it turns on the pump. ( If we use the solar and rechargeable (for night time) batteries it's a long last . And using esp board we can also disable the signal from RF ransmitter and also switch on and off the motor wireless and get the feed back also .it's my thoughts to make a project any suggestions please share And we can also use Lora boards for flat buliding .

[@techiesms]

RF fails in my case we can give it a try to LoRa. May be that will work

Firstly asking subscribers regarding their ideas and discussing the things is very good If is make this kind of project i will use electrodes as i want to know the level of water and a buzzer when overflow Is there any other way to know the level of water without any disadvantages like ultrasonic sensor

[@techiesms]

Knowing the level of water is good, but extending such long wires is hectic. that's why I said, I made this project just for my home. If you have a single storey house you can easily extend the wires and know the level as well. But to know the level I'll recommend that floating switch rather than dipping electrodes
