ChipCap—The Fully Calibrated
Humidity and Temperature Sensor
The ChipCap series humidity sensor by GE 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. 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).
Accurate, Repeatable Humidity and
Temperature Measurement
ChipCap provides either analog or digital interfaces on
a single, 5VDC-powered chip. The package is highly
resistant to chemical vapors and other contaminants.
ChipCap sensors are precalibrated and offer high
interchangeability. They also fully recover from
condensing environments and may be used across a
wide range of both temperature and relative humidity
ranges.
ChipCap relative humidity sensors change capacitance
in direct proportion to ambient relative humidity. An
internal solid-state band gap transistor provides
temperature measurement. This integral design
reduces overall cost and complexity and improves
reliability.

Small, Integrated Package for
Automated Assembly
ChipCap contains the entire signal conditioning circuitry
on a single silicon die. The sensor and circuitry are
integrated into a small footprint SoC to save board real
estate. ChipCap is shipped in tube packaging for
automated insertion on surface mount technology
(SMT) circuit boards. Tape and reel packaging is
available upon request for high volume applications.
