Adafruit AGS02MA I2C TVOC Gas Sensor

The AGS02MA is a compact, MOX-based TVOC sensor designed for efficient gas resistance measurement, providing output in parts-per-billion (ppb) through I2C integration. With its affordable and compact design, it is well-suited for simple TVOC monitoring applications.

Specifications and Benefits:

• Miniature ADC chip for accurate readings.
• Operates on a 20KHz I2C clock rate, compatible with select processors like RP2040, ESP32, and ATmega328.
• Operates at both 3V and 5V, eliminating the need for level shifting.
• Requires two 10K pullup resistors for I2C bus connection.

The sensor excels in scenarios where tracking ambient volatile organic compounds is necessary, but keep in mind it does not perform additional filtering or calculations.

Before usage, ensure compatibility with your system’s I2C frequency using an oscilloscope or logic analyzer, as non-compatible chipsets like SAMD21 and SAMD51 may not support this sensor.
