Datasheet ZMOD4510 (IDT)

Gas Sensor Module for ZMOD4510 Outdoor Air Quality Datasheet Description Features
The ZMOD4510 Gas Sensor Platform detects outdoor air quality in  Measurement of outdoor air quality, including ppb trace gas a variety of indoor and outdoor applications. The module is a 12- concentrations of nitrogen oxides (NOx) and ozone (O3) pin LGA assembly (3.0  3.0  0.7 mm) that consists of a gas  Supports international standards for total outdoor air quality, sense element and a CMOS signal conditioning IC. The module’s such as the US Environmental Protection Agency (EPA) sense element consists of a heater element on a silicon-based  MEMS structure and a metal-oxide (MOx) chemiresistor. The Heater driver and regulation loop for constant resistance, minimizing effect of environmental temperature on signal signal conditioner controls the sensor temperature and measures the MOx conductivity, which is a function of the gas concentration.  Internal auto-compensated temperature sensor; not stress sensitive The sensor module is optimized for the detection of trace atmospheric gases, including nitrogen oxides (NO  I2C interface: up to 400kHz x) and ozone (O3). The ZMOD4510 is targeted for monitoring the Total Outdoor  Configurable alarm/interrupt output with static and adaptive Air Quality giving an Air Quality Index (AQI). levels The measurement results can be read via an I2C interface with the  Built-in nonvolatile memory (NVM) for user data user’s microprocessor, which processes the data to determine the  Low average power consumption in low mW range levels of gases present and to indicate the AQI based on  Supports low-voltage and low-power battery applications international standards. With its low operating current, the ZMOD4510 is an excellent choice for low-voltage and low-power  No external trimming components required battery applications. Built-in nonvolatile memory (NVM) stores the  External reset pin (active-LOW) configuration and provides space for arbitrary user data.  Customization for mobile, industrial, and consumer applications
