The ZMOD4510 Gas Sensor Module is designed for monitoring outdoor air quality (OAQ) and the measurement of outdoor relevant gases ozone and nitrogen oxide. It is a 12-pin LGA assembly (3.0 x 3.0 x 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 Si-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 outdoor air concentration. 

The measurement results can be read via an I2C interface with the user’s microprocessor, which processes the data to determine an Outdoor Air Quality Rating defined by the US Environmental Protection Agency. Software upgradability makes the sensors in the ZMOD4510 platform capable of providing a variety of measurement options by varying the method of operation or changing the firmware used to interpret the measurements for gas selectivity. Downloadable firmware libraries and source code provided by IDT enables detection of OAQ Rating and supports smart devices implementation. The ZMOD4510 is ideal for outdoor air quality applications such as smart home building controls and other smart personal devices.
