Weather Station

#1
Has anyone written some software to take 4-20mA inputs from a weather station and generate web pages from the data?

We are looking into doing this for boat clubs.

Cheers

I have a Y13 student about to start his A2 Electronics project doing just this. I'll let you know how he gets on!

I have not done any PICAXE work with 4 to 20 mA signals but from the hardware perspective if you think about how PLC analogue input cards typically function, they in fact have (or did have) a 250 Ohm resistor across the input.
With the 4 to 20 mA current flowing, this gave a voltage of 1 Vdc at 4 mA and 5 Vdc at 20 mA.
Then you can just use the standard ReadADC command.

Which weather station equipment are you using?
Much of the equipment I have seen details for in the past is based on 1-Wire comms.
