Product Highlights

  • I2C digital interface up to 3.4 MHz


  • Indoor air quality
  • Home automation
  • Internet of things
  • Weather forecast
  • GPS enhancement (e.g. time-to-first-fix improvement, dead reckoning, slope detection)
  • Indoor navigation (change of floor detection, elevator detection)
  • Outdoor navigation, leisure and sports applications
  • Vertical velocity indication (rise/sink speed)


  • Digital interface
    1. I2C (up to 3.4 MHz)
  • Current consumption
    1. 2.1 µA ar 1 Hz humidity and temperature
    2. 3.1 µA at 1 Hz pressure and temperature
    3. 3.7 µA at 1 Hz humidity, pressure and temperature
    4. 0.09-12 mA for p/h/T/gas depending on operation mode
    5. 0.15 µA in sleep mode
  • Key parameters for gas sensor
    1. Response time: <1 s (for new sensors)
    2. Power consumption: <0.1 mA in ultra-low power mode
    3. Output data processing: direct indoor air quality (IAQ) index output
  • Key parameters for humidity sensor
    1. Response time: ~8 s
    2. Accuracy tolerance: ±3% r.H
    3. Hysteresis: ±1.5% r.H
  • Key parameters for pressure sensor
    1. RMS Noise: 0.12 pa, equiv. to 1.7 cm
    2. Offset temperature coefficient: ±1.3 Pa/K, equiv. to ±10.9 cm at 1 °C temperature change
