Hello
I would need advice
how Reading data with weather station 433 mhz.
I have arduino UNO
433mhz receiver ( mk rx 5v 433mhz )
is good receiver ?
Please help (manual, tutorial, )
well thank you
Youtube and Google it. There are great walkthrough tutorials.
If your weather station is a commercial product you bought, you need to figure out its protocol first. If it's something you made yourself, well, never mind, I doubt that.
does not work 
GND connect GND
VCC connect VCC
DATA connect to D2
/*
- Demo for RF remote switch receiver.
- For details, see RemoteReceiver.h!
- This sketch shows the received signals on the serial port.
- Connect the receiver to digital pin 2.
*/
#include <RemoteReceiver.h>
void setup() {
Serial.begin(115200);
// Initialize receiver on interrupt 0 (= digital pin 2), calls the callback "showCode"
// after 3 identical codes have been received in a row. (thus, keep the button pressed
// for a moment)
//
// See the interrupt-parameter of attachInterrupt for possible values (and pins)
// to connect the receiver.
RemoteReceiver::init(0, 3, showCode);
}
void loop() {
}
// Callback function is called only when a valid code is received.
void showCode(unsigned long receivedCode, unsigned int period) {
// Note: interrupts are disabled. You can re-enable them if needed.
// Print the received code.
Serial.print("Code: ");
Serial.print(receivedCode);
Serial.print(", period duration: ");
Serial.print(period);
Serial.println("us.");
}

Of course that won't work for a weather station.
and How do I read 433MHz signal?
