Datasheet IDT ZMOD4510

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 12pin 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,
 The sensor module is optimized for the detection of trace
atmospheric gases, including nitrogen oxides (NOx) and ozone
(O3). The ZMOD4510 is targeted for monitoring the Total Outdoor
Air Quality giving an Air Quality Index (AQI). 
 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
configuration and provides space for arbitrary user data.  Typical Applications  
