I'm doing a project on "measurement of temperature using a Rover"
AS a part of this we need to measure the temperature of the
surroundings and transmit this temp. value. For transmiting the
temperature I decided to use FM transmission and for temp. sensing I
decided to use LM35.For displaying temperature value at the reciever I
decided to atm microcontroller(89c51)

So if any one knows the details regarding this Temperature
transmission . plz send me the details.


Maybe encode the temperature as an audio frequency? LM331 can convert both
ways, so two of those will do it. You can feed the audio signal directly
into the processor, too, if the FM receiver keeps the amplitude steady.
This might be the simplest way to avoid noise errors in your readings.
