The ZMOD4510 gas sensor platform detects air quality in a variety of indoor and outdoor applications. The module is a 12-pin LGA assembly (standard version 3.0mm x 3.0mm x 0.7mm) 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 resistance, which is a function of the gas concentration.​

The freely available firmware enables different ZMOD4510 features based on traditional and machine learning algorithms with embedded artificial intelligence (AI) using the same hardware platform. This is used to determine the Air Quality Index (AQI) output, which is based on the gases present. 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 latest ultra-low power mode, the ZMOD4510 is an excellent choice for detecting ozone and nitrogen dioxide in indoor and outdoor applications.

ZMOD4510 Gas Sensors for Outdoor Air Quality Applications Overview

This video gives a general overview of the ZMOD4510 outdoor air quality gas sensors from Renesas. The ZMOD4510 is the first software-upgradeable, digital outdoor air quality sensor for high volume applications. This sensor is capable of detecting ozone (O3) and nitrogen oxides (NOx) gases, two significant causes of unhealthy outdoor air quality. The ability of the ZMOD4510 to quantify combined ozone and NOx in concentrations as low as 20 parts per billion (ppb), coupled with its outstanding combination of flexibility, miniature form factor and waterproof packaging option makes it an ideal solution for a wide variety of industrial and consumer applications.
