●The ZSSC3123KIT is an evaluation kit that contains software and hardware needed for communication and calibration of cLite family ZSSC3123 capacitive sensor signal conditioner. The ZSSC3123 is a CMOS integrated circuit for accurate capacitance to digital conversion and sensor specific correction of capacitive sensor signals. Digital compensation of sensor offset, sensitivity and temperature drift is accomplished via an internal digital signal processor running a correction algorithm with calibration coefficients stored in a non volatile EEPROM. A PC can communicate with a ZSSC3123 socketed on the SSC evaluation board via the SSC communication board (SSC CB) through a USB connection. The software should function on any Windows 2000/XP/Vista/Windows 7 system after installation of a USB driver. The SSC evaluation board can connect to a capacitive sensor or provide on board capacitors for simulating input from a capacitive sensor.
