Gas Sensor Module for TVOC ZMOD4410 and Indoor Air Quality Datasheet Description Features
The ZMOD4410 Gas Sensor Module is designed for detecting total  Sensor output based on AI machine learning algorithmic: volatile organic compounds (TVOC), estimating CO2, and • Measurement of total organic compounds (TVOC) monitoring indoor air quality (IAQ) in different smell based use concentrations and indoor air quality (IAQ) cases, including very humid and dusty applications with the possibility of water spray, condensation, or immersion. It is a 12- • Module algorithm estimates carbon dioxide level (eCO2) LGA assembly (3.0 × 3.0 × 0.7 mm) that consists of a gas sense • Algorithm to set a control signal to trigger an external element and a CMOS signal conditioning IC. The module’s sense action based on IAQ and odor change element consists of heater element on a Si-based MEMS structure • Algorithm to discriminate sulfur based odors and a metal oxide (MOx) chemiresistor. The signal conditioner  Heater driver and regulation loop for constant resistance, controls the sensor temperatures and measures the MOx minimizing effect of environmental temperature on signal conductivity, which is a function of the gas concentration. The measurement results can be read via an I2C interface with the  Customization for mobile, industrial, and consumer user’s microprocessor, which processes the data. applications The provided firmware enables different ZMOD4410 features  Internal auto-compensated temperature sensor; not stress sensitive based on traditional and machine learning algorithms with an embedded artificial intel igence (AI). This is used to determine the  I2C interface: up to 400kHz TVOC concentration, IAQ rating, and estimated carbon dioxide  Built-in nonvolatile memory (NVM) for module-specific data (eCO2) level. Alternatively, depending on the operation mode, the  Very low average power consumption down to 1.5mW ZMOD4410 algorithm can discriminate between sulfur-based odors or generate a control signal, which can trigger actions based on  Excel ent for low-voltage and low power battery applications total odor levels. With its low operating current consumption in Low  No external trimming components required Power Operation Mode, the ZMOD4410 is an excel ent choice for  External reset pin (active-LOW) low-voltage and low power battery applications. Built-in nonvolatile  Siloxane resistant memory (NVM) stores the module configuration and calibration data.  RoHS compliant  Supply voltage: 1.7V to 3.6V
