LM35 on logomatic

[case-sensitive]

Its Melbourne, luckily only 3° minimum. (luckily it does not go below 0 because 3° outside means 3° in your bedroom as well, at least in a weatherboard house. Otherwise maybe 8°C)
Anyhow, so the sensors should be fine, somehow 2° to 100°, the latter maybe in my black roof on a 45° day. (was not me, only moved in last week)

seems if I use a power supply instead of batteries the readings become more stable.
