The sensor and circuitry are measurement. Based on a capacitive polymer sensing integrated into a small footprint SoC to save board technology, this device offers signal conditioning and real estate. ChipCap is shipped in tube packaging for temperature compensation for a single SoC (Systemon- automated insertion on surface mount technology (SMT) Chip) solution. The device is very simple to use, fully circuit boards. Tape and reel packaging is available upon tested and calibrated for accuracy on deliveryno request for high volume applications. further calibration is needed. 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 Digital Inter face humidity range. Long term stability is excellent. The temperature accuracy is 1C from 0C to +70C. Dual V supply outputs provide humidity and temperature as 0V to 1V, 3V to 5.5V 8 NC NC 7 or 0.5V to 4.5V ratiometric or available with digital output RH Sensor (the ZACwire one-wire interface). 9 NC NC 6 0.1 10 NC NC 5 V+ GND C Accurate, Repeatable Humidity and 11 4 ChipCap 12 NC NC 3 Temperature Measurement 13 NC NC 2 OUT-RH OUT-T ChipCap provides either analog or digital interfaces 14 1 on a single, 5VDC-powered chip. The package is highly resistant to chemical vapors and other contaminants. Gnd ChipCap sensors are precalibrated and offer high interchangeability. They also fully recover from condensing environments and may be used across a Analog Inter face wide range of both temperature and relative humidity ranges.
