ZMOD4410
Gas Sensor Module for TVOC and Indoor Air Quality
Description
Features
■
The ZMOD4410 Gas Sensor Module is designed for
easy implementation to detect total volatile organic
compounds (TVOC), estimate CO2, and monitor indoor
air quality (IAQ). The module works reliably in various
conditions, including very humid and dusty applications
with the possibility of water spray, condensation, or
immersion. The small LGA assembly consists of a gas
sense element and a CMOS signal conditioning IC. The
sense element is a Si-based microhotplate with a robust
and highly sensitive metal oxide (MOx) chemiresistor.
The signal conditioner (ASIC) controls the sensor
temperatures and measures the MOx conductivity,
which is a function of the gas concentration. The
measurement results are easily read via an I2C
interface with the user’s microprocessor, which
processes the data.
Sensor output based on AI machine learning
algorithmic:
●
Absolute measurement of total organic compounds
(TVOC) concentrations and indoor air quality (IAQ)
to meet UBA air quality standard
●
●
Estimated carbon dioxide level (eCO2)
Absolute TVOC output to meet Public Building Air
Quality (PBAQ) standards
●
●
Relative IAQ based on TVOC and odor changes
Algorithm to discriminate sulfur-based odors
■
■
High sensitivity to Hydrogen (H2) based on resistance
output
Heater driver and regulation loop for constant
resistance, minimizing effect of environmental
temperature on signal
■
■
■
Built-in nonvolatile memory (NVM) for module-
specific data (configuration and calibration)
The firmware configurable platform quickly enables
different ZMOD4410 features based on machine
learning algorithms and embedded artificial intelligence
(AI) with Renesas pre-trained models and algorithms.
This is used to determine and output TVOC

concentration, IAQ rating according to UBA, and
estimated carbon dioxide (eCO2) level. Alternate
algorithms and firmware implementations can output an
absolute TVOC concentration to meet Public Building
Air Quality (PBAQ) standards; a relative IAQ rating
based on total VOC and odor levels changes or
discriminate between sulfur-based odors. With the ultra-
low operating current consumption implementation, the
ZMOD4410 is an excellent choice for low-voltage and
ultra-low power battery applications.
