Gas Sensor Module for
Outdoor Air Quality
ZMOD4510
Datasheet
Description
The ZMOD4510 Gas Sensor Platform detects outdoor air quality in
a variety of indoor and outdoor applications. The module 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 consists of a heater element on a silicon-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 device is ideal for monitoring and reporting Total Outdoor Air
Quality. The Air Quality Index (AQI) output is based on a
combination of outdoor gases present, including nitrogen oxides
(NOx) and ozone (O3).
The measurement results can be read via an I2C interface with the
user’s microprocessor, which processes the data to determine the
levels of gases present and to indicate the AQI based on
international standards. With its low operating current, the
ZMOD4510 is an excellent choice for low-voltage and low-power
battery applications. Built-in nonvolatile memory (NVM) stores the
module configuration and calibration data.
