Justanotherprogrammer:
I'm sorry I can't send the paper my leader won't allow it. The app is being developed as of now so is the web based system... But I will answer questions. Kindly list down the questions please and I will answer them the best I can. Thank you.

So you want help to build a system that represents the paper you rote to prove your paper theory BUT are not allowed to show us the paper but want us to throw questions at you to see if we can guess the papers design.

You must be kidding!
You can ask your leader to reevaluate that idea or you will not get much help.

Whats a water sensor brick (check brick, if wet raining, if missing may have been washed away. Flood warning)
If not by wireless then by wire. Check cost of wire compaired to wireless and why did you not cover this in your 'Paper'.
Sent to server how?
Sent to apps, How?
Covering what area?
If you work on rising water level in the street to warn people in the street this seems redundent to feed this to an app?

Begins to sound like your first post should have read,

HAVE BEEN ASKED TO PRESENT PAPER ON FLOOD SYSTEM TO TEACHER PLEASE DOCUMENT SYSTEM AND POST HERE.
THANK YOU SIR/MAAM.

So go talk to the leader about that paper and come back with your specifications of this system and what you want help with.
Then people here can help you!

Ps the brick idea is not so bad. Tie a string from brick to a bell and if bell starts ringing the flood water is washing away the brick. So please evacuate.

You sense water levels using ultrasonic distance sensors attached to the underside of bridges.

Simple and it provides far more information than a simple float switchs and the 'device' is a self contained box with no external wires etc.

23

A very effective flood warning device is very simple and already in use world-wide.

People with cell phones call others to report high water. Slightly more sophisticated folks can also post high water warnings on Facebook.

Good day!

We need your guidance to fellow programmers my teammates and I will create a system called flood monitoring using Arduino and a water level sensor and I was wondering if we can put statistics for this type of system like the:

Date and time the flood was detected.
History of flood data received by the Arduino (daily, weekly, monthly, semi annually and annually)

I was wondering if this is possible and how?

Thank you

25

Everything is possible. The impossible just takes a little longer.

If you are going to record data for any length of time you'll need to include SD card or transmit capabilities to upload. A real-time clock (RTC) like the DS1307 to record date and time and some serious power management.

@Justanotherprogrammer, please do not cross-post. Threads merged.

On the hardware front, an ultrasonic echosounder is MUCH more effective as this measures surface runoff as well as flood conditions.

An example of what you are trying to achieve would be the spot sensor, and is already a cheap, effective and developed piece of tech using LoRaWAN protocol to communicate over vast distances with very little power consumption - http://www.spotsen.se/

I used to work for the Urban Observatory in Newcastle where we work with exactly this kind of technology. www.uoweb1.ncl.ac.uk

I build & sell a device that does what you’re planning.
The biggest two problems - fouling of the sensor, and battery life.

Ensure your float/sensor is either self cleaning, of well protected from getting tangled with grass, weeds, mud etc.

My units use an SLA battery that provides mass to keep the units stable - and provide more than 3-days operation between charges (or solar operation).

of course - if like me, you use mobile communications - you need cellular coverage!

And indeed Oxford have implemented such a sytem as well.
