ENS160 is a digital multi-gas sensor specifically designed for indoor air quality monitoring

ENS160 is a digital multi-gas sensor specifically designed for indoor air quality monitoring, offering optimum detection of a wide range of gases and volatile organic compounds (VOCs), including toluene, hydrogen, ethanol, NO₂, and ozone.

Based on ScioSense innovative TrueVOC™ technology, ENS160 combines the flexibility of four independently controlled sensor elements, based on metal oxide (MOX) technology, with intelligent on-chip algorithms to calculate CO₂-equivalents, TVOC, and various air quality indices (AQIs).

The LGA packaged device offers an SPI or I²C slave interface with a separate supply for host communication.

Key features

• Detection of reducing (VOCs) and oxidizing gases (e.g., NO₂)
• Multiple IAQ outputs (TVOC, eCO₂, AQI)
• On-chip data processing
• High immunity to siloxanes and humidity

Additional features

• Warm-up time: less than 1 minute
• Initial start-up time: less than 1 hour
• Supports up to 4 independent MOX gas sensors
• Integrated pre-calibrated sensor fusion and automatic baseline correction algorithms
• Integrated sensor measurement and heater drive control
• Wide operating ranges:
  • Temperature (T): -40 to +85 °C
  • Relative humidity (RH): 5 to 95%
• High-speed I²C and SPI interfaces
• Separate digital I/O supply pin:
• V_DDIO: from 1.71 to 3.6 V
• Configurable interrupt engine:
  • Polarity, pin configuration, events
• Raw sensor data also available
• Low peripheral BOM required
• Compact size: 3.0 x 3.0 x 0.9 mm LGA package
• Tape & reel, reflow solderable
