Image of Silicon Labs Si7034 Sensor Silicon Labs' Si7034 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 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.

The humidity and temperature 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 calibration or software changes required.

The Si7034 is available in a 2x2 mm DFN package and is reflow solderable. It can be used as a hardware- and software-compatible drop-in upgrade for existing RH/temperature sensors in 2x2 mm QFN-6 packages. The Si7034 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.
