🔹 Overview
The 7Semi ENS160 Air Quality Sensor I2C Probe is a digital indoor air quality sensor module based on the ScioSense ENS160 gas sensor.
  • Designed for multi-parameter air quality monitoring
  • Uses metal-oxide (MOX) sensing technology
  • Provides processed digital outputs via I2C
It measures air pollution indicators rather than individual gas concentrations.
🔹 Working Principle
  • Uses a heated MOX (Metal-Oxide) sensing element
  • Gas molecules (VOCs, oxidizing gases) change sensor resistance
  • Internal ADC + DSP convert signal → air quality metrics
  • Built-in algorithms perform:
    • Baseline correction
    • Environmental compensation (temperature/humidity)
🔹 Measured Outputs
The sensor provides processed digital values:
  • TVOC (Total Volatile Organic Compounds):
    • Range: 0 – 65,000 ppb
  • eCOâ‚‚ (Equivalent COâ‚‚):
    • Range: 400 – 65,000 ppm
  • AQI (Air Quality Index):
    • Qualitative air quality level
👉 Important:
  • eCOâ‚‚ is estimated (not real COâ‚‚ measurement)
🔹 Detectable Gases
The sensor responds to a wide range of indoor pollutants, including:
  • Ethanol
  • Toluene
  • Hydrogen
  • Volatile organic compounds (VOCs)
  • Oxidizing gases
🔹 Electrical Characteristics
  • Supply Voltage:
    • Core: 1.71V – 1.98V
    • I/O: 1.71V – 3.6V (typically 3.3V)
  • Interface:
    • I2C (primary for probe version)
    • SPI supported internally
  • I2C Address:
    • 0x52 or 0x53 (selectable)
🔹 Environmental Operating Range
  • Temperature: –40°C to +85°C
  • Humidity: 5% to 95% RH (non-condensing)
👉 Suitable for indoor and industrial environments
🔹 Internal Features
  • On-chip air quality algorithms
  • Humidity & temperature compensation
  • Automatic baseline correction
  • Raw data access (for advanced processing)
🔹 Functional Behavior
  • Requires warm-up time (~few minutes) for stable readings
  • Continuously measures air and updates:
    • TVOC
    • eCOâ‚‚
    • AQI
  • Output is ready-to-use (no external calibration needed)
🔹 Key Technical Features
  • Multi-parameter air quality sensing (TVOC, eCOâ‚‚, AQI)
  • Digital I2C output (easy MCU integration)
  • Built-in compensation algorithms
  • Wide detection range
  • Compact probe-style design
  • Stable long-term operation
🔹 Functional Advantages
  • No need for:
    • External ADC
    • Complex gas calibration
  • Provides interpretable air quality data directly
  • Works well in smart home and automation systems
🔹 Limitations
  • Does not measure true COâ‚‚ (only equivalent estimation)
  • Sensitive to:
    • Temperature/humidity changes
    • Airflow conditions
  • Requires good ventilation for accurate readings
  • MOX sensors may drift over long-term use
🔹 Technical Summary
The ENS160 I2C Probe is a smart air quality sensor that:
  • Converts complex gas interactions into simple digital metrics
  • Uses internal intelligence instead of raw sensing
  • Is optimized for indoor environmental monitoring systems
