## Description

The AGS02MA is a compact MOX-based TVOC (Total Volatile Organic Compounds) gas sensor with an I2C interface. It features a built-in ADC that outputs gas resistance and parts-per-billion (ppb) readings — higher ppb values indicate more organic compounds in the air. This is a simple, inexpensive sensor that provides raw TVOC readings without additional filtering or calculations. It works with both 3V and 5V logic, so no level shifting is required. Two 10K pull-up resistors are needed for the I2C bus connection. Key Features TVOC Detection – Measures volatile organic compounds in parts-per-billion (ppb) I2C Interface – Digital output with built-in ADC 3V/5V Compatible – No level shifting required Compact Size – Miniature MOX sensor package Warning: This sensor requires a 20KHz I2C clock rate. It will not work at 100KHz or 400KHz. Confirmed working on RP2040, ESP32, and ATmega328 (Arduino UNO). Does not work on SAMD21 or SAMD51. Verify your board supports 20KHz I2C before purchasing. Ideal For Indoor air quality monitoring VOC detection in enclosed spaces Simple environmental sensing projects Package Contents 1× AGS02MA TVOC gas sensor Note: Two 10K pull-up resistors are required for the I2C bus connection (not included).
