dallas sensors did log init value of 85 celsius to max, now
it starts adding to max only if celsius is below 70.
the last 2 dallas sensors displayed identical values,
because in the index SensorsT I've put the messurements
for them starting with 1, while the dallas lib starts counting
with 0. obviously it returns the messurement of the last sensor
if you try to access a sensor id which doesn't exist (in my case
this was 4, which would have been 3).
re-calibrated the lux formula, which didn't match measurements done
with a luxmeter. Constant 500 => 5000.0.
