Si7005开发套件是一款数字式相对湿度和温度传感器。This monolithic CMOS IC integrates temperature and humidity sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C host interface. The patented use of industry-standard,low-K polymeric dielectrics for sensing humidity enables the construction of a low-power, monolithic CMOS sensor IC with low drift and hysteresis and excellent long term stability.Both the temperature and humidity 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 Si7005 is packaged in a 4x4 mm QFN package and is reflow solderable. The optional factory-installed protective cover offers a lowprofile, 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 Si7005 offers an accurate, low-power, factory-calibrated digital solution ideal for measuring temperature, humidity, and dew-point in applications ranging from HVAC/R and asset tracking to industrial and consumer platforms.产品特性
