LEGO Sensors

Dacta (the educational division of LEGO) has a number of sensors available as part of their science and technology products. In addition, the #8479 Barcode Truck set contains a new version of the touch sensor. It looks like all of these sensors are compatible with LEGO's new Mindstorms product, though it remains to be seen if LEGO will start to offer any sensors as S@H service packs. Presently, the only ways to purchase individual sensors is through Pitsco, the single distributor of Dacta products. The sensors fall into two categories: passive (a resistance is measured), and active (the device consumes power). All of the dacta sensors have built in leads that terminate in the standard 2x2 electrical plate. The new touch sensor requires a separate lead. The various sensors are listed below:
