ScioSense ENS160 air quality sensor

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

Applications

• Air purificationwwjh/home automation
• HVAC/ventilation systems
• Building automation/smart thermostats

Available tools

ENS160 Evaluation Kit is comprised of a PCB hosting ScioSense ENS160 air quality and ScioSense ENS210 temperature & humidity sensor and an additional I2C to USB bridge. The evaluation kit is powered and connected to a Windows PC via a USB port. It can be controlled by a Windows PC-based application (ENS160 Dashboard), which displays and logs the available sensor outputs (air quality, humidity & temperature). The dashboard can be downloaded from the ScioSense website. The evaluation kit can also be used for quick integration into the end customer's application using the I2C interface. Integration is supported by Dashboard quick start guide, sensor-specific datasheets, application notes, and drivers, available online.
