Description
Description
The HDC302x is an integrated capacitive based relative humidity (RH) and temperature sensor. It provides high accuracy measurements over a wide supply range (1.62 V – 5.5 V), along with ultra-low power consumption in a compact 2.5-mm × 2.5-mm package. Both the temperature and humidity sensors are 100% tested and trimmed on a production setup that is NIST traceable and verified with equipment that is calibrated to ISO/IEC 17025 standards.
Features
- Supply voltage: 1.62 - 5.50V
- i²C interface suitable for up to 1MHz speeds
- Average power consumption: approximately 0.4µA
- Four selectable I2C addresses and data protection via CRC checksum
Temperature Sensor
- Operating range: -40°C to 125°C
- Accuracy: ±0.1°C typical*
- NIST traceability: relative humidity & temperature
Relative Humidity Sensor
- Operating range: 0% to 100%
- Accuracy: ±0.5% typical*
- Offset error correction: reduces the offset to bring the device within the accuracy specification
- Long-term drift: 0.19%RH/year
- Condensation protection with integrated heater
