Raspberry Pi temperature (and humidity and pressure) logger – full instructions!


A while ago I reported on progress towards a Raspberry Pi based environmental logger.

Well, it has proved to be quite popular at work (several laboratories now use them to log temperature and humidity values for around £100 each device) so I wrote up pretty much all the instructions on how to build More >
