Gas Sensor Module for
Outdoor Air Quality
ZMOD4510
Datasheet
Description
Features
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.

Measurement of outdoor air quality, including ppb trace gas
concentrations of nitrogen oxides (NOx) and ozone (O3)
Supports international standards for total outdoor air quality,
such as the US Environmental Protection Agency (EPA)
Heater driver and regulation loop for constant resistance,
minimizing effect of environmental temperature on signal
Internal auto-compensated temperature sensor; not stress
sensitive
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).

I2C interface: up to 400kHz
Configurable alarm/interrupt output with static and adaptive
levels

Built-in nonvolatile memory (NVM) for module-specific data
Low average power consumption in low mW range
Supports low-voltage and low-power battery applications
No external trimming components required
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.
