Gas Sensor Module for
TVOC and Indoor Air Quality ZMOD4410 Datasheet Description Features The ZMOD4410 Gas Sensor Module is designed for detecting total
volatile organic compounds (TVOC) and monitoring indoor air
quality (IAQ). It is a 12-pin LGA assembly (3.0 x 3.0 x 0.7 mm) that
consists of a gas sense element and a CMOS signal conditioning
IC (IDT’s ZSSC3250). The module’s sense element consists of
heater element on a Si-based MEMS structure and a metal oxide
(MOx) chemiresistor. The signal conditioner controls the sensor
temperature and measures the MOx conductivity, which is a
function of the gas concentration. Measurement of total organic compounds (TVOC)
concentrations and indoor air quality (IAQ) Module algorithm estimates carbon dioxide level (eCO2) Multiplexed input channel for heater, resistance, and
temperature measurements Heater driver and regulation loop for constant heater voltage
or constant heater resistance Internal auto-compensated temperature sensor; not stress
sensitive The measurement results can be read via an I2C interface with the
user’s microprocessor, which processes the data to determine the
TVOC concentration, IAQ rating and estimated carbon dioxide
(eCO2) level. With its low operating current consumption, the
ZMOD4410 is an excellent choice for low-voltage and low-power
battery applications. Built-in nonvolatile memory (NVM) stores the
configuration and provides space for arbitrary user data. I2C interface: up to 400kHz Configurable alarm/interrupt output with static and adaptive
levels Adjustable ADC resolution for optimal speed versus
resolution: 16-bit maximum Built-in nonvolatile memory (NVM) for user data Extremely low average power consumption in low ВµW range Typical Applications Excellent for low-voltage and low-power battery applications Indoor air monitoring No external trimming components required Monitor home, office, and personal environments for healthy
conditions and comfort Detect hazardous materials and unhealthy conditions …
