Gas Sensor Module for ZMOD4510 OAQ targeting NO2 & O3 Datasheet Description Features The ZMOD4510 Gas Sensor Platform detects air quality in a variety Sensor output based on operation method: of indoor and outdoor applications. The module is a 12-pin LGA Non-selective measurement of nitrogen dioxide (NO ) and 2 assembly (standard version 3.0 3.0 0.7 mm) that consists of a ozone (O ) 3 gas sense element and a CMOS signal conditioning IC. The Selective ozone (O ) measurement using ultra-low power 3 modules sense element consists of a heater element on a silicon- Supports international standards for air quality, such as the based MEMS structure and a metal-oxide (MOx) chemiresistor. US Environmental Protection Agency (EPA) The signal conditioner controls the sensor temperature and Customization for mobile, industrial, and consumer measures the MOx resistance, which is a function of the gas applications concentration. Heater driver and regulation loop for constant resistance, The device is ideal for monitoring and reporting Outdoor Air minimizing effect of environmental temperature on signal Quality (OAQ). The provided free firmware enables different 2 ZMOD4510 features based on traditional and machine learning I C interface: up to 400 kHz algorithms with an embedded artificial intelligence (AI) using the Built-in nonvolatile memory (NVM) for module-specific data same hardware platform. This is used to determine the Air Quality Ultra-low average power consumption down to 0.2 mW Index (AQI) output, which is based on gases present. The outdoor Excellent for low-voltage and low-power battery applications air quality includes nitrogen dioxide (NO ) and ozone (O ). 2 3 Alternatively, depending on the operation mode, the ZMOD4510 No external trimming components required can measure selectively ozone in an ultra-low power (ULP) External reset pin (active-LOW) operation. Siloxane resistant The measurement results can be read via an I2C interface with the RoHS compliant users microprocessor, which processes the data to determine the Target operation temperature: -40C to +65C levels of gases present and to indicate the AQI based on international standards. With its latest ultra-low operating current Supply voltage: 1.7V to 3.6 V consumption, the ZMOD4510 is an excellent choice for low-voltage Water and dustproof version available (IP67 certified) and low power battery applications.
