Description
The Si7015 I
2
C Humidity and Temperature Sensor is a monolithic CMOS
IC integrating humidity and temperature sensor elements, an analog-to-
digital converter, signal processing, calibration data, and an I
2
C Interface.
The patented use of industry-standard, low-K polymeric dielectrics for
sensing humidity enables the construction of low-power, monolithic
CMOS Sensor ICs with low drift and hysteresis and excellent long term
stability.
Each unit is 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. The
Si7015 can be used as a drop-in upgrade for the Si7005 with only minor
software changes because the register sets are the same, and the
4x4 mm QFN package is footprint-compatible with that of the Si7005.
The device is compatible with standard SMT assembly processes, such
as reflow. The optional factory-installed cover offers a low profile and
convenient means of protecting the sensor during assembly (e.g., reflow
soldering) and throughout the life of the product, excluding liquids
(hydrophobic/oleophobic) and particulates.
The Si7015 offers an accurate, low-power, factory-calibrated digital
solution ideal for measuring humidity, dew-point, and temperature in
applications ranging from HVAC/R and asset tracking to industrial and
consumer platforms.

After RTL8019AS is initialized, the values of the registers read are all 0x00?
Why do I read the register values of all 0x00 after initializing RTL8019AS? What is the reason? How can I find it? Please help! !...
