RE: 1-wire Samples

["Jon Whiten" <jon@xxxxxxx>]

I have had one of the evaluation units now for around 6 months and have had
it on/off the 1-wire net since then.  It has been fairly reliable on the
bench but totally killed the 1-wire net when it got foggy with the sensor
outside.

Anyway, I intend to try it again outside but have it powered from a 5V
supply rather than letting it rely on the parasite power from the 1-wire
net.

Incidentally, the evaluation unit does have provision to add a photodiode
(transistor?) and resistor to implement the light sensor part.

Regards,

Jon
