SENS-SI7021 SI7021 Temperature & Humidity Sensor for 3.3V-5VDC Micro-Controllers

SI7021 I2C Temperature & Humidity Sensor for 3.3V- 5VDC Micro-Controllers

The SI7021 I2C Humidity & Temperature Sensor is a highly accurate, low-power solution for measuring both humidity and temperature. This monolithic CMOS IC integrates humidity and temperature sensing elements, an analog-to-digital converter (ADC), processing, and calibration data—all packaged into a compact 3x3 mm DFN package. With its factory-calibrated sensors and I2C interface, the SI7021 offers a seamless and efficient solution for a wide variety of applications. 

Features:

• Factory-Calibrated Sensors: Both the humidity and temperature sensors are pre-calibrated, with calibration data stored in the on-chip non-volatile memory.
• Low Power Consumption: The SI7021 operates with minimal power, making it ideal for battery-powered devices.
• Wide Operating Range: The sensor can accurately measure humidity from 5% to 95% RH and temperature within a range of -30°C to 190°C.
• I2C Interface: The built-in I2C communication interface simplifies integration into existing systems, making it easy to add precise humidity and temperature sensing to any project.
• Low Hysteresis & Long-Term Stability: Low-K polymeric dielectrics for humidity sensing, the SI7021 sensor provides minimal hysteresis.
• Compact Size: The SI7021 is 3x3 mm.
• Plug-and-Play Compatibility: The sensor is hardware- and software-compatible, making it a simple upgrade for existing systems without requiring changes to your setup.
• Built-in Pull-up Resistor: The branch board includes a 4.7kΩ pull-up resistor for I2C communication.
