Description
The TH02 is a digital relative humidity and temperature sensor. This
monolithic CMOS IC integrates temperature and humidity sensor
elements, an analog-to-digital converter, signal processing, calibration
data, and an I2C host interface. The patented use of industry-standard,
low-K polymeric dielectrics for sensing humidity enables the construction
of a low-power, monolithic CMOS sensor IC with low drift and hysteresis
and excellent long term stability.
Both the temperature and humidity sensors are factory-calibrated and the
calibration data is stored in the on-chip non-volatile memory. This ensures
that the sensors are fully interchangeable, with no recalibration or
software changes required.
