Key Features
High Precision Sensing:
Humidity: Measures 0-100%RH with up to 1.8%RH accuracy, even in condensing environments.
Temperature: Detects -40°C to 125°C with 0.2°C accuracy, suitable for extreme conditions.
Efficient Power Management:
Operates on 3.3V-5V with minimal power draw: 0.4 μA average current at 1Hz sampling and 80 nA in idle mode, perfect for battery-driven IoT devices.
Reliable Data Communication:
Uses I2C Fast Mode Plus (400kHz) with CRC checksum to ensure data integrity.
Fixed I2C address 0x44 for straightforward setup in multi-sensor networks.
Industrial-Grade Durability:
JEDEC JESD47 qualification ensures robustness in harsh environments.
Variable power heater prevents condensation on the sensor surface, maintaining measurement stability.
NIST traceability provides traceable calibration for professional and industrial use.
Plug-and-Play Integration:
Compatible with STEMMA QT Qwiic interfaces, reducing wiring complexity for Arduino, Raspberry Pi, and microcontroller projects.
