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.
