Normally, the agriculture lands are far away from home, due to which we have to go to the fields for irrigation. I want to do something that farmers can irrigate their fields by sitting at home using mobile APP. how it can be possible
I believe that camera will be needed to do this to see the actual position And to control the pump and pipe flow, HARDWARE will be required
Have you seen or developed something like this
Well I was going to say something about getting hold of a local marijuana grower, but really how does this differ from a typical lawn irrigation system, have you looked to see what is already available?
Or scale this up and you have a center pivot irrigation used by farmers.
Jim
It takes longer By using technology
So true!
I believe that camera will be needed
More useful would be things like soil moisture sensors, weather sensors, links to weather forecasts, etc ...
Have you seen or developed something like this
Yes, automated irrigation systems are commonplace.
EDIT
Can farmers irrigate crops sitting at home using mobile app?
Can they? Yes, it's very much within the realm of things that are possible today.

See the actual position of what? Obviously, hardware will be required, as software alone can't do much.
how it can be possible
There is no limit to this. It could be as simple as a relay connected to a GSM/Wifi module, operating a pump motor, or as difficult as hundreds of individually controlled flow points with cameras, soil sensors and other such telemetry connected to a central controller/server.
From your post history, what you haven't seem to understood despite multiple telling-offs is that such wide, open-ended questions are useless to everybody, yourself included. These are forums where you can ask for help specific to a problem you're having while implementing something with an AVR, not ask for generalized ideas and solutions to problems you might some day want to tackle.
See the actual position of what?
I think (s)he means "position" as in "situation" or "conditions" or "status"

Ah okay. I guess moisture sensors would be a lot more useful.
And fly a drone out every day or so to check on things.
Farmers have been doing exactly this for years. Any of the so-called "center-pivot" sprinkler systems do it. Usually, around here (here = Western United States) it is timed and the system just works. Some systems even allow fertilizer to be injected into the sprinkler system. Such things have been going for well over 25 years. Wikipedia says they were invented in 1952. Common size is 400m line length (e.g. radius of the circle it covers). There are also corner-pivot systems that cover a 90 degree sector of a circle.
Now, they are even more highly automated. It is possible to vary the water delivery rate along the pipe in real time to suit the plant and soil conditions through the circle. Farmers are using drones to monitor field conditions. All this is part of what is now called "precision agriculture".
What the OP proposes is common practice, already, at least in the U.S.
At the other end of the scale is drip irrigation. It is widely used in Europe. I presume that it is used elsewhere. These systems are (or CAN BE) automatically controlled, usually by timers. Sometimes soil moisture sensors are added. Marijuana growers were the early big users in the U.S. Now, I use drip in my garden. Cannot imagine not using it.
Jim
"Agri-Tech" is another term: https://en.wikipedia.org/wiki/Agricultural_technology
Marijuana growers... Now, I use drip in my garden.
Or rather, "What ARE you telling us?!!"
We had a couple of legal marijuana plants 2 summers ago. Have been using drip for close to 20 years. Its a no brainer for us.

I searched for it on the internet I noticed they use moisture sensor for such type of system. I talked about the camera because I thought it would be good. we will irrigate the plants by watching real-time videos, The disadvantage of the sensor is that if a sensor becomes damaged, then we will not get the correct information, due to which crop can also be ruined.
Ok, how many sensors can I need? Do I have to use a sensor for each floating-point? Which system will be better GSM-based or WiFi-based
The communications medium is independent of the sensor selection. Basically, you can use any sensor with WiFi, or BlueTooth, or GSM, or LoRa, or wired telephone. It makes no difference. Sensor outputs get encoded as digital data. As long as the communication medium can carry digital data, who cares what is the sensor?
The number of sensors depends on the crop and the variability of soil type, sun vs shade, and such. I have seen nurseries that had one sensor per plant type. I have seen 200m center pivots with several within the circle. Again, it all depends. Each farmer figures it out, trial and error.

Our allotment shed has an Arduino with a SIM800 module and a PAYG SIM, powered by solar. I've set it up for timed irrigation with overrides by SMS text messaging. I'll probably upgrade it to a 4G mifi router so we can watch live cameras on the bird feeders and owl nesting box. There's a thousand and one other things that could be done, e.g. intrusion detection, logging environmental data to a cloud service, etc.
The disadvantage of the sensor is that if a sensor becomes damaged, then we will not get the correct information
This, of course, is an issue for any remote monitoring/control system!
Therefore, the system itself and the human operator(s) need to be "sanity checking" the sensor readings, and checking when there are "unusual" readings.
Of course, cameras also fail!
Ok, how many sensors can I need?
How long is a piece of string?
Do I have to use a sensor for each floating-point?
It depends.
Which system will be better GSM-based or WiFi-based
It depends.
Engineering is always about trade-offs; analysing the situation and requirements, considering the pros & cons of various options, and coming up with whatever best fits all the requirements & constraints.
I was actual more impressed when my neighbor seeded corn.
Om a triangular field he just totally double seeded at the ends.
The computer system knew where there had been seeded and closed the rows off. (one by one)
(I don't know which GNSS they use, and probably more than one, normal GPS has to big an error)
Add just a late comment til #17
differential GPS will only give about +-2 meters on something that moves.
(I don't know which GNSS they use, and probably more than one, normal GPS has to big an error)
Probably differential GPS

I really don't think you're finished with the analysis of the problem yet - far too soon to be diving into specific hardware details!
Quote:GSM module / Wifi Module
Have you rejected all the other options Jim mentioned in #13 ?
And that was by no means an exhaustive list!
I really don't think you're finished with the analysis of the problem yet
Ok, we first decide what should be in a good irrigation system. Once the features of the system are fixed, we can think about how we can achieve them.
According to you, which system would you call a good irrigation system?
According to me, a better system would be one in which farmers could irrigate their crops from home. the farmer can irrigate his crops without going to the fields.
first decide what should be in a good irrigation system
Exactly.
And a key source for what constitutes a "good" irrigation system must, surely, be the farmers - don't you think?
You should also study what is the current "state of the art" - ie, what are others doing in this field?
(not much point in spending time to just come up with something that's inferior to what's already in the market)
a better system would be one in which farmers could irrigate their crops from home.
Why should they have to be at home?
Why should they have to worry about it at all?
without going to the fields
Perhaps farmers like going to their fields?
Don't forget to consider the possible downsides of not having people in the fields; eg, theft, disease, pests, ...
Why should they have to be at home?
There are some farmers whose farm are far away from their homes. so they want to save their travelling time They want a system that can irrigate their crops from home. I think it can be possible with modern technology Now I have a requirement whose solution I want to find out
I wrote:

I think you missed my point!
I meant, why should they have to be specifically at home - ie, why should they not be at any other location away from their home?
They want a system that can irrigate their crops from home.
Again, have you actually asked them?
I think it can be possible with modern technology
As others have already said it's been possible - and has been done - for decades now!
Now I have a requirement
Do you have an actual requirement? Or are you just thinking that there might be a requirement?
Again, have you researched the current state of the art with automated irrigation ?
I think you missed my point!
Sorry for not being able to explain the project requirements correctly I want to develop a system for farmers, so they can irrigate their crop from anywhere.
Again, have you researched the current state of the art with automated irrigation?
I have done research on the internet for this. I found that mostly moisture sensors are used with microcontroller and WiFi, or BlueTooth, or GSM, or LoRa, or wired telephone to build such a system. The sensor senses the humidity of the ground and the system decides whether to supply water to the crop or not. a farmer can on / off the motor pump through the mobile app from any location

Before researching the technology I'd start with a bit of market research. And if you do that you can also take the opportunity to ask them the kind of things they prefer - equipment, sizes, longevity of equipment., ballpark perceived market value etc etc.I want to develop a system for farmers, so they can irrigate their crop from anywhere
I Have talked to many farmers Where I live, farmers still do farming in a traditional way The farmer wants to work with farming as well as others field because farming does not earn much anymore
they want to save their time so they can invest their time for other works
I (sic?) have done research on the internet for this.
have you?

Sounds like you've just copied that straight from posts in this thread!
So, now that you (sic) have found that's what's already on the market, how do you - as a complete newcomer to the field - intend to compete with these established players ?
If you talk to farmers, you may find some very different requirements,
For example, the farmer who grows corn or wheat will have very different needs from the vegetable famer who sells produce at a village market, Even the corn farmer who grows on several hectares may be quite different from one who grows on a half hectare for market.
I suggest that you actually speak, in person, to a variety of farmers in your region.
In your defense, irrigation automation, which is what you are describing, has very different requirements in different places, different cultures, and different climates. There IS room for regional specialty equipment. That said, you really do need to do your market research, because your hunches can be very wrong. For example, I live in an area where irrigation is not used much, and where it is used, it is often with "big gun" sprinklers that are pulled through the crop or fixed set sprinklers on risers. The irrigated crops tend to be grown close to where the farmer lives. The large acreage crops are grown without irrigation. So, what I write about center-pivot applies to a totally different area but is still very common.
So, please do your market research. If you don't, you are very likely to waste a lot of time, energy, and money.
Jim
