Hab gerade 2 samples von diesem netten sensor erhalten. Aus der Produktbeschreibung:
The MC34940 is intended for cost-sensitive applications where non-contact sensing of objects is desired. When connected to external electrodes, an electric field is created. The MC34940 detects objects in this electric field. The IC generates a low-frequency sine wave, which is adjustable by using an external resistor and is optimized for 120 kHz. The sine wave has very low harmonic content to reduce harmonic interference. The MC34940 also contains support circuits for a microcontroller unit (MCU) to allow the construction of a two-chip E-field system.

bin nun dabei eine platine fuer den chip zu entwerfen. besoderes highlight...ich stell endlich auf smd widerstaende und kondensatoren um :) --Wizard23 22:09, 7. Feb. 2007 (CET)
