I am developing a sensro network compliant to the IEEE 1451 instrumentation standard. the humidity sensor that i am using for this purpose is
HCH-1000-001 ..
i need help to know how to construct the cct to connect this sensor to PIC16F877
this is the sensor data sheet
**broken link removed**

The capacitance of the transducer varies as the humidity varies. You could set up an oscillator with the device acting as the charge/discharge capacitor. The frequency would vary due the the varying capacitance. Specific frequencies would relate to specific humidities.
