Features: Precision Relative Humidity Sensor ± 3% RH (max), 0–80% RH High Accuracy Temperature Sensor ±0.4 °C (max), –10 to 85 °C 0 to 100% RH operating range Up to –40 to +125 °C operating range Wide operating voltage (1.9 to 3.6 V) Low Power Consumption 150 µA active current 60 nA standby current Factory-calibrated I2C Interface Integrated on-chip heater 3x3 mm DFN Package Excellent long term stability Optional factory-installed cover Low-profile Protection during reflow Excludes liquids and particulates Applications: HVAC/R Thermostats/humidistats Respiratory therapy White goods Indoor weather stations Micro-environments/data centers Automotive climate control and defogging Asset and goods tracking Mobile phones and tablets The 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 RH/ temperature sensors in 3x3 mm DFN-6 packages, featuring precision sensing.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 recalibration or software changes required. Package Included: 2* Si7021 Industrial High Precision Humidity Sensor
