Thanks a lot.
The code will be easy. The biggest problem is the hardware. If the data is coming in serial TTL (0/5V, as you mention) then you need to know the data rate, when to expect each value. Once you have that information, then you can search on serial input basics and read through the thread on how to read in and interpret serial information.
Post back the timing information or the datasheet and you will be able to make some more progress.
Use the serial port (or some version of SoftwareSerial) to read the data. Be sure to connect all the grounds. You may find the Serial Input Basics tutorial useful.
Post a link to the data sheet or product page of the sensor.
Seems like standard serial protocol, 19200 Baud.
I would use AltSoftSerial.

That depends on the Arduinio. OP which one are you using?
Soo....had no succes so far reading with the simplest arduino serial code reading.
Are you saing that i basisicly need another hardware device?
Why is not ArduinoUno able to read it?
All the grounds are connected, since the receiver is using only 30mA and powered from the arduino 5v supply.
Why is not ArduinoUno able to read it?
How could we possibly know?
Please read and follow the directions in the "How to use this forum" post. Post the code, using code tags, and a clear schematic diagram showing all your wiring.
