DHT22 using rf transmission

Hi
I'm pretty new to ardunio and was hoping to get some help.
I want to set up a DHT22 to read temp and humidity, then I want to send that data through an 433hz rf transmitter and read the receiver data in arduino ide, eventually I will put my data on different software to view graphicly but this is my first step in the road to the finished project.
I've seen lots of examples but they all end up showing the data on a LCD, I don't want that.
I'm using 2 unos, on to transmit the other to receive
Any help would be great

Start by working with the DHT22. Look for example code. During that work You use Serial Monitor to verify the function.

When that works, proceed in the same way with the wireless part.

but they all end up showing the data on a LCD,

To start just change lcd.print to Serial.print. Make sure that there is a Serial.begin(baud rate) in setup and that the serial monitor baud rate matches.

I've seen lots of examples but they all end up showing the data on a LCD, I don't want that.

That is somewhat like saying you can't learn anything from a tutorial on making wooden boxes because they use pine and you want to use oak. Don't use examples as a source for cut-and-paste. Use them as a basis for demonstration and understanding, and also read the documentation for what you want to do, then put it all together.

@aarg
Well written. Code is not a pill one buys in the drugstore. It's way more advanced, diversified.....
Understand the principle..... That was my environment being thrown into numerous of large projects finding bugs, cleaning up the issues left by earlier colleagues.
