Hi,

I want to be able to read analogue voltages remotely using telemetry with a
distance of say 200 metres between Tx and Rx.

What is the cheapest and simplest method using a PIC for example ?

Ideally, the Rx should be able to output the voltage reading in RS232 format
so that a PC can show the reading on the screen.
But a relayed ananlogue output would be ok.

Any help appreciated.

Thanks.

Darren
