The AGS02MA is a compact MOX-based TVOC sensor module designed for cost-effective air quality monitoring. It integrates a miniature ADC that directly converts gas resistance into digital I²C output, reporting values in parts per billion (ppb). Though it does not include onboard filtering or advanced signal processing, it provides fast and simple detection of volatile organic compounds in the environment. With its small footprint and low power consumption.
