ChipCap

Fully Calibrated Humidity and Temperature Sensor The ChipCap series humidity sensor offers a new standard in the field of accurate relative humidity measurement. Based on a capacitive polymer sensing technology, this device offers signal conditioning and temperature compensation for a single SoC (System-on-Chip) solution. The device is very simple to use, fully tested and calibrated for accuracy on delivery—no further calibration is needed.   Product Description ChipCap can be incorporated into an assembly or finished sensor to meet customer specifications. The measurement is accurate to ± 2% from 20% to 80%RH and ± 3% across the entire humidity range. Long term stability is excellent. The temperature accuracy is ± 1°C from 0°C to +70°C. Dual outputs provide humidity and temperature as 0V to 1V, or 0.5V to 4.5V ratiometric or available with digital output (the ZACwire one-wire interface).
