Summary of ENS160 IS A DIGITAL MULTI-GAS SENSOR SPECIFICALLY DESIGNED FOR INDOOR AIR QUALITY MONITORING
ENS160 is a digital multi-gas indoor air quality sensor using ScioSense TrueVOC™ MOX technology with four independently controlled sensing elements and on-chip algorithms to report TVOC, eCO2, and AQI. It offers high immunity to siloxanes and humidity, fast warm-up, integrated sensor fusion and baseline correction, and high-speed I2C/SPI interfaces with a separate VDDIO supply and configurable interrupt engine.
Parts used in the ENS160 Project:
- ENS160 LGA packaged multi-gas sensor
- MOX sensor elements (up to 4 independent elements integrated in ENS160)
- On-chip microcontroller/processing for sensor fusion and algorithms
- I2C or SPI slave interface circuitry
- Separate VDDIO supply pin (1.71 to 3.6 V)
- Heater drive control (integrated)
- Interrupt pin and polarity/pin configuration circuitry
- Power supply supporting operating temperature and humidity ranges
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.
