Si7021 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.
Patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of low-power, monolithic CMOS Sensor ICs with low 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 recalibration or software changes required.
Si7021 is available in a 3x3 mm DFN package and is reflow solderable.
It can be used as a hardware- and software-compatible drop-in upgrade for existing Featuring precision sensing over a wider range and lower power consumption.
Si7021 offers an accurate, low-power, factory-calibrated digital solution ideal for measuring humidity, -point, and temperature, in applications ranging from /R and asset tracking to industrial and consumer platforms.
