ENS220 barometric pressure and temperature sensor

ENS220 Premium accuracy barometric pressure and temperature sensor for activity tracking and indoor navigation/localization

Premium accuracy barometric pressure and temperature sensor for activity tracking and indoor navigation/localization.

The ENS220 is an ultra-low-power, high-accuracy barometric pressure and temperature sensor. It comes in the smallest size LGA package with digital I2C and SPI interfaces. This enables new use cases in activity tracking, indoor navigation/localization, fall- and liquid-level detection.

The capacitive pressure sensor of the ENS220 is integrated on a CMOS ASIC. This single die solution not only allows small form factor packages with excellent immunity to changes in environmental conditions, but also achieves ultra-low current consumption due to the capacitive read-out.

ENS220 features and benefits

Features:

  • Absolute / Relative accuracy: ±0.5 hPa / ±0.025 hPa (±2.5 Pa is equivalent to a height of ±20 cm in air)
  • Lowest power: average supply current of 0.1 μA at idle, 0.8 μA when sampling at 1/60 Hz
  • Ultra-low noise of 0.1 Pa rms (≈ 1 cm in air) at 2 Hz sample rate
  • User-configurable sample rate up to 1 kHz (0.9 Pa rms)
  • Temperature accuracy of 0.1 K with 8 mK resolution
  •  Fully digital interface with best-of-breed form factor

Benefits:

  • Reliable cm resolution positioning and differential pressure measurements
  • Perfectly integrates into space-constraint designs, e.g. mobiles, wearables, hearables
  • Long battery life even at high sampling rates
  • Minimal peripheral BOM requirements
