<font color="blue">No home can be complete without a gamma-ray counter, so I've now written a driver for a DS2438 too:

<font face="Courier New">/sys/bus/w1/devices/26-xxxxx/cca
............................/etm
............................/temperature
............................/ others
</font id="Courier New">
The idea of using a DS battery-monitoring chip came from here:

You could always use it to detect muons from cosmic rays too!

Now all we need now is one that reads gasses/fumes (co2) to see if your neighbourhood is not a highway (smoke) area

I've now attached a Figaro TGS2602-B00. It has a little 56mA heater in it and needs to be conditioned by leaving it in fresh air for a week.

I'm not sure where I can get that in England though!
