Goodmorning everyone. I wish I could transmit the data of my weather station with RF module 433 mhz.
I'm not practical about programming. could someone please integrate the transmission in the schetck below? thanks
I have tried in every way for more than 5 months but without results. here I am attaching the working and clean program

Which RF module 433 MHz module do you have?

More members will see your code if you post your code as described in the how to use this forum sticky.
It is unlikely that anyone will write code for you for free. If you want someone to write code, you could ask a moderator to move this thread to the Gigs and Collaboration section. Use the Report to Moderator button to make the request.
I didn't ask to write all the code from scratch. the code of the working weather station is there. I appeal to the goodwill of someone. I am a student who would like to make a nice project. if nobody wants to help me I'll make it right.

You won't get much goodwill posting the same question in different parts of the forum
TOPIC MERGED.
Could you take a few moments to Learn How To Use The Forum.

It will help you get the best out of the forum.
sorry if I opened the same topic in another section. having had problems with the internet, I never saw my place again and then republished it. I didn't want to create any confusion. Sorry

And you will learn a lot more if you do make it work.
Rather than ask someone to complete your project for you, study the examples provided in the library you are using for the modules you have.
Once they are working think how you could adapt the libraries working code to your project.
I have written programs of this type, for other 433mhz systems, turning that standalone program into a transmitter and receiver pair I would suggest is non trivial, its not as you seem to imagine a couple of minutes work.
Please note that the abbreviation for megahertz is MHz (As subtly pointed out by TheMemberFormerlyKnownAsAWOL in reply #1).
The SI unit Hz gets a capital letter because it is named after Heinrich Hertz.
The multiplier for mega- is a capital M. A small m is used to indicate milli-.
So that means that by using a small m you are wrong by a factor of 109.
Meanwhile, when people have finished scoring points...
I have just gone wireless with a project .. just so that I don't have to have a long wire connecting the sensors, arduino and screen. I found the biggest issue was converting more than one parameter to a string. I assume your weather station measures more than one thing? The Strlen command can concatenate (three parameters in the example linked below) into a single word.. for the 433 to send/receive... and Strtok can decode the word back into 3 measurements. Very cute.

But also check out these, as they helped me understand how the Txr & Rxr better...
Be aware that with this method the measurement resolution drops from 1024 to 255 - that's worth thinking about, if accuracy is important?
Good luck with your project. Try not to wind people up in here by not reading the rules etc !! LOL some of the guys here are utterly brilliant at what they do.. and they will teach you so much, for free. But they wont just do it for you ! And when you say you are not great at coding, and you've been at this for 5 months... I worry - if this project doesn't get you excited and keen to learn even more to help you discover the amazing things C++ and a soldering iron can do.. then maybe this isn't for you in the long term?
Hope you enjoy it.
...but make sure you spell them "strlen" and "strtok" etc, because, unlike "MHz", they're not derived from the name of an actual person.
