Description:The Si7021 I2C Humidity and Temperature Sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digitalconverter, 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 Featuring precision sensing over a wider range and lower power consumption.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.Specification:Power supply : 3-5VRelative humidity: ± 3% RH (max), 0-80% RHTemperature: ±0.4°C (max), -10 to 85°COperating range: 0 to 100% RHOperating range: Up to -40°C to +125 °CWide operating voltage: 1.9V - 3.6VLow power consumption: 150 μA active currentStandby current: 60 nASize: 1.3*1cm/0.51*0.39"Applications:HVAC/RThermostats/humidistatsRespiratory therapyWhite goodsIndoor weather stationsMicro-environments/data centersAutomotive climate control and defoggingAsset and goods trackingMobile phones and tabletsPackage includes:1 x GY-21 Humidity Sensor
