ENS220 Barometric Pressure and Temperature Sensor

The ENS220 compact barometric pressure sensor from ScioSense combines high accuracy, ultra-low-power consumption, and high data rate capabilities

Image of ScioSense ENS220 Barometric Pressure and Temperature SensorScioSense's ENS220 is a high-speed, ultra-low-power, and high-accuracy barometric pressure and temperature sensor. This is achieved by integrating both the sensor membrane and the ASIC in a single monolithic die using all CMOS processes.

As a result of this construction, the chip size is minimized, allowing the use of a 2 mm x 2 mm LGA package for space-critical applications. It also enables applications to benefit from high speed, low noise, and high resolution as a consequence. Absolute accuracy of ±0.5 hPa and relative accuracy of ±0.025 hPa allow reliable centimeter resolution for applications monitoring height changes and positioning. In addition, the sample rate is user-configurable up to 1 kHz, enabling free fall detection applications. Battery-operated devices can benefit from low power consumption, with a supply current of 0.1 µA in idle mode or 0.8 µA when sampling at 1/60 Hz. The integrated temperature sensor compensates the pressure output and provides a 0.2 K accuracy, with both values being available through standard, fast, and high-speed I²C and SPI.

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 and space-saving 2 mm x 2 mm LGA package
Applications
  • Mobile/wearables: activity tracking, indoor localization/navigation, fall detection
  • Gaming, AR/VR, drones: height tracking
  • Appliances/HVAC: filter clogging detection
  • White goods: liquid level detection
  • Medical: blood pressure measurement
  • Weather stations
  • Accurate temperature meters for gasses and surfaces
