ZMOD4410
Gas Sensor Module for
TVOC and Indoor Air Quality
ZMOD4410
Datasheet
Description
The ZMOD4410 Gas Sensor Module is designed for detecting total
volatile organic compounds (TVOC) and monitoring indoor air
quality (IAQ) in different use cases. It is a 12-pin LGA assembly
(3.0 3.0 0.7 mm) that consists of a gas sense element and a
CMOS signal conditioning IC. The module’s sense element con-
sists 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.
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. Alternatively, depending on the operation mode, the
ZMOD4410 software can generate a control signal, which can
trigger actions based on odor levels. With its low operating current
consumption in Low-Power Operation Mode, the ZMOD4410 is an
excellent choice for low-voltage and low-power battery appli-
cations. Built-in nonvolatile memory (NVM) stores the configuration
and provides space for arbitrary user data.
Typical Applications
Indoor air monitoring
Monitor home, office, and personal environments for healthy
conditions and comfort
Detect hazardous materials and unhealthy conditions
(e.g., fumes from construction materials)
Automation based on indoor ambient air quality (HVAC, air
purifiers, thermostats, etc.)
Available Support
ZMOD4410 Evaluation Kit
Manuals, application notes, blog, and white papers
Instructional videos
Programming libraries, example codes, and
algorithm support to optimize performance
Third-party certification for compliance with
well-accepted international IAQ standards
Features
