ScioSense ENS220

The ENS220 is an ultra-low-power, high-accuracy barometric pressure and temperature sensor with outstanding speed and resolution.

Its innovative monolithic, all CMOS processed capacitive sensor element and ASIC is packaged in a small 2x2 mm LGA housing and can communicate through digital I2C and SPI interfaces.

The integrated design of the sensor results in low noise, high resolution, accuracy and speed, all of which enable use cases in activity tracking, indoor navigation/localization, fall- and height-level detection.

Key features

• Absolute / Relative accuracy: ±0.5 hPa / ±0.025 hPa allows positioning applications
• Ultra-low-power consumption enables long battery lifetime
• User-configurable sample rate up to 1 kHz
• Absolute accuracy: ±0.5 hPa

Additional features

• Relative accuracy: ±0.025 hPa (equiv. to ±20 cm) allows ultra-fine differential pressure measurements for reliable centimeter resolution positioning
• Lowest power consumption: 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) 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
• Standard, fast, and high speed I²C and SPI interface
• Small 2.0 x 2.0 x 0.75 mm³ LGA package
