The SI7015 I²C 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 I²C Interface. 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 4mm x4mm QFN package is footprint-compatible with that of the SI7015.

The SI7015 offers an accurate, low-power, factory-calibrated digital solution ideal for measuring humidity, dew-point, and temperature in a number of indusrtrial and consumer applications.

Applications of the SI7015 include:

HVAC/R , Thermostats, Instrumentation , White goods, Weather stations, Asset tracking and storage. All I²C Mini Modules are designed to operate at 5VDC. This Mini Module includes on-board power regulation and PCA9306 I²C level-shifting circuitry to adapt to our 5V I²C standard. Using a convenient 4-Pin plug, devices can be daisy-chained onto the I²C Bus, eliminating the need for soldering. Plug together all the pieces you need for your next automation application.

Pull-up resistors are included with all ControlEverything.com master devices. If you are wiring in your own I²C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.
