Home / Products / Environmental Sensors / ENS220 Barometric Pressure and Temperature Sensor

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 0.2 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
