Item:191819866081无标题文档 >Description The 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 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 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 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 particulates The Si7021 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 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 Size: 1.3*1cm/0.51*0.39" Package Include:1PCS Si7021 Industrial High Precision Humidity Sensor I2C Interface for Arduino >Payment We only accept payment through Paypal.
