Frequently Asked Questions

What is the output interface and protocol of the AGS02MA sensor?

The AGS02MA provides a calibrated digital output via the I2C communication protocol. This allows for direct connection to microcontrollers like Arduino, ESP32, or Raspberry Pi using just two wires (SDA and SCL), simplifying data acquisition and integration.

What is the operating voltage range for this module?

The module is designed to operate from a supply voltage between 3.3V and 5.5V DC. This wide range makes it compatible with both 3.3V logic systems (common on modern microcontrollers) and traditional 5V Arduino boards without requiring a level shifter.

How long does the sensor need to preheat before taking accurate readings?

The sensor requires a preheat time of at least 120 seconds (2 minutes) after power-on to stabilize its sensing element. For the most accurate and consistent TVOC measurements, it is recommended to allow for this initial warm-up period before relying on the data.

What gases does the AGS02MA sensor detect?

The AGS02MA is a Total Volatile Organic Compound (TVOC) sensor. It detects a wide range of volatile organic compounds commonly found indoors, such as formaldehyde, benzene, toluene, and other solvents, providing a composite concentration reading in ppb or µg/m³.
