Wireless WaterLevel and Pump On/Off System using NRD24L01 Modules

Katper

Hello;

I am completely new to this site and also to arduino, i have basic knowledge of electronics and arduino. So i want to make a project for my home, it will not be just a prototype but i will use it in my home.

So i want to make a wireless overhead tank water level monitor system using nrf24L01 modules (or any other suitable wireless module), which will display water level in perentage from 0 to 100 on LCD and also which will control relay based on the predefined water levels. This will also have a manual button to turn on/off relay at any time.

Here is what i have planned so far;

I will use waterproof ultrasonic sensor to measure water level at transmitter side, whiich will send the data using nrf24l01 modules to reciever, which will convert/map the distance to percentage and it will be shown to 16*2 lcd, if water level has reached 20% the relay/pump will be turned on and when the tank is full or 100% the relay will be turned off. There should be a manual button to turn on/off pump at any time.

So anybuddy here can write the code for that system? I have basic knowledge of arduino programming, i can do few things but cant write entire code myself.

If anybuddy has better idea he can also share here.

Looking forward and Thanks

    Thanks for your input.

    I have already watched those videos and searched yt as well before writing here, almost all the tutorials on yt are for wired system, since my overhead tank is at 4th floor so its not practical for me to use wired system, as we know that those nrf modules are dirt cheap, they will cost less than using wire ig, so thats why i am looking for wireless system.

    That's why I said that it may help as a starting point.

    If you were to set that example up on the 4th floor, then you would have a self-contained working system just without the remote control and monitoring down below.

    Add the wireless nrf24 module, initialise it, then start sending the water level value every time it is read in the loop. Your receiving node down below can listen for that water level value and display it to the LCD display, using the same code as used before.

    Add the manual control button to the receiving node down below and start transmitting its state. The node on the 4th floor listens for this and goes into manual mode, using the same code as before.

    In the overall design you will probably want to keep in mind what happens when your wireless link fails due to interference or low signal level. 'Dirt cheap' RF isn't always reliable.
