Control water pump dry run

Hi, am new with arduino though am going to use it in ma final year project to contro water pump and also prevent the dry run. Anyone to guild me on different approaches i can use to prevent the dry run and how can i make it more unique ,,,,just suggestions i will appreciate ......with code

or any similar or relatable project can share ....thats the idea in my mind just asking any guildance/help guys for the same

I suggest you draw a block diagram showing what you are thinking about, take a picture of it and post on your thread.

@sanareh, your topic has been moved to a more suitable location on the forum; the question is general and not specific to Emergency Response: Covid-19 Projects

There are many ways to monitor a pump against loss of prime.
Pressure switch, flow meter, load current monitoring.
Depends a lot on your installation and it's requirements.

My first thought is to get a pump.
And an Arduino.
And some sort of sensor.
Sensor should be one thay can detect water.

Then connect them and write a sketch to control the pump.
Make sure you stop the pump if the sensor does not detect water.

First.
List the types of pumps that move water.
Each has uses and benefits. Each has applications where they work and do not.
Make/find an application for pumps. Deep well pumps, high pressure etc.

Second: for each type of pump list how it can fail.
Third: research what is used to protect the pump from failing. What sensors what logic what controls. ETC.

With what you created, select the pump that fits the application.
Select the sensors that works for that pump.

Then search online for that type of sensor and use the word arduino

Example:
Arduino pump pressure.

When you write your paper you will be very knowledgeable about pumps and applications.

When you have problems with your code. Post your code and we can help you figure it out

Thanks sir for positive feedback...this is what am trying to get ma self into....hope u can see ma attached block diagram.

hello sir...this now ma block diagram am trying to figure out....now ma question is,,,,,in ma dry run detection unit,,,which sensor can i use apart( have seen IFR sensor useful for just presentation case) flow sensors because this will actualize the project presentation with real water but i do want to demonstrate ma idea with more complications. Still i want to improvise the water pump, is that possible/logical?

"on ma thread" ?// where is this feature mr paul...cant see it.

Ok, now explain where the water comes from that your pump is going to pump. Is it a storage tank of some sort? A river? A small stream, A well? All will require a different method of determining if water is available for pumping.

a submersible pump will be submersed in water when in operation.
water detection could be by a float switch.

a sump-pump that is in a dry pit, but ready to pump water when it enters the pit could use a float switch or use an ultrasonic level detector

a peristaltic pump pulls water up from a lower source so you need to know that there is fluid a the source.

some pumps are 'self priming' so are designed to run dry for a bit.

I can keep going but this is your work. the sensor is dependent on the pump and the application.

only you know your application and with that, you need to find a sensor that works for your application.

it should not take an hour to get all the answers in post#7
and find the sensor that works for you.

or, we could play that game where we say, use 'this' and you say it can't work because of 'that'
so we say use this other thing
and you say, that won't work because of this other thing

I'll start, use a float switch.

Ok...i need to pump from a tank[quote="Paul_KD7HB, post:13, topic:884879, full:true"]

OK....i need to pump from tank

Ok, so you need to know when the tank is empty, so the pump will not be turned on.
Are float switches appropriate for the tank?
