Cory Smith sent the following email in response to the above posting:
I saw your posting on the rcx newsgroup. What are DCP sensors? Where can I
find out about the ones Lego offers?
Thanks.
Cory Smith
I think this question is best answered in a public forum. Lego now offers seven
different DCP Microsense sensors in addition to their own Lego sensors. These
can be found in the new Pitsco catalog, which is not posted on their web pages
as of 02/25/00.
These sensors require a Lego adapter for the RCX, which Pitsco sells for $54
USD. This Lego adapter has a wire brick on one end with a long wire and a four
pin adapter on the other end. There are over a dozen DCP sensors, but the ones
Lego remarkets are:
Humidity $179
Air Preasure $135
Motion/Position $95 (an accurate angle sensor with 1 degree settings)
Protemp $49 (a rapid response temperature sensor)
Sound $75
Ph $75
Voltage $49
Pitsco offers all seven sensors for $625.
These sensors are not built for Legos, so they do not have any convenient
mountings. This is paticularly annoying with the motion/position sensor which
has a spindle that is not the same geometry as the Lego axles. If you securely
mount these sensors on a Lego invention, you will have to devise unique
mounting structures.
The marketing implication of these sensors is they are offered for the new
datalogging features supported by Robolab in Investigator. In reality these
sensors can be used in any Robolab program. Robolab even supports a generic DCP
sensor by using voltage ranges.
Nqc, pbForth, and LegOs should already be able to support the DCP sensors.
I do have some minor issues/questions pending with Dacta on using some of these
sensors, but they do work well! My only problem is the cost. To use the
cheapest sensor requires a 54 dollar adapter along with the 49 dollar sensor.

| Does anyone know of a second source for the new sensors the RCX now supports? These would be the DCP microsense sensors. If you thought the Lego sensors were expensive at $10-$28 USD, the Lego prices for DCP sensors start at $50. They want $95 USD (...) (25 years ago, 24-Feb-00, to lugnet.robotics.rcx.robolab)
