Si7021 Industrial High Precision Humidity Sensor With I2c Interface

brand new and high qualityThe 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. 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 stabilityThe 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 requiredThe 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 over a wider range and lower power consumption. The optional factory-installed cover offers a low profile, convenient means of protecting the sensor during assembly (e.g., reflow soldering) and throughout the life of the product, excluding liquids (hydrophobic/oleophobic) and particulatesThe Si7021 offers an accurate, low-power, factory-calibrated digital solution for ideal for measuring humidity, dew-point, and temperature, in applications ranging from HVAC/R and asset tracking to industrial and consumer platforms Features:Precision Relative Humidity Sensor 3% RH (max), 080% RHHigh Accuracy Temperature Sensor0.4 C (max), 10 to 85 C0 to RH operating rangeUp to 40 to +125 C operating rangeWide operating voltage (1.9 to 3.6 V)Low Power Consumption 150 A active current60 nA standby currentFactory-calibratedI2C InterfaceIntegrated on-chip heater3x3 mm DFN PackageExcellent long term stabilityOptional factory-installed coverLow-profilefor Protection during reflowExcludes liquids and particulates Applications:HVAC/RThermostats/humidistatsRespiratory therapyWhite goodsIndoor weather stationsMicro-environments/data centersAutomotive climate control and defoggingAsset and goods trackingMobile phones and tabletsSize: 1.3*1cm/0.51*0.39"Quantity:1pc
