Re: DS18S20 temperature ic sockets

["Simon Coates" <ecolume@xxxxxxx>]

Stephen,

The diode helps prevent ringing - ie. signal reflections on larger
installations.
I put the diode in series with a 2 pin header so I can use a jumper to
select the diode if necessary.  Since the diodes cost only pennies I
added
them on all my PCBs - 18 in total.

brass
transistor heat sink to give the sensor some extra latency.
