LM35 output and RF communiction

[nalawade]

I want to send the output of LM35 temperature sensor over the RF network. Is it possible to send the data over the RF network withour microcontrollers.

LM 35 gives output voltage which needs to be converted into digital output. How to send the digital data using RF communication

 

[BigBoss]

There are some communication micro-controllers with RF parts for ISM bands in the market that are used to transmit/receive analog/digital signals.
Their software is already well written except User Interface.You can build-up a system with these ICs.

You can use a voltage-to-frequency convertor (VCO), which output frequency can modulate an RF signal.

See page 17 of the datasheet:

At the receiver side after the demodulator, can use a simple frequency counter to read the corresponding temperature values.
