Asair AGS10 TVOC Gas Sensor Module - MEMS Semiconductor, Digital Output

The AGS10 provides a calibrated digital signal output, simplifying direct connection to microcontrollers like Arduino or Raspberry Pi without the need for external analog-to-digital converters (ADCs). The output is typically in ppb (parts per billion) or a graded scale for TVOC concentration.

The module requires a stable 3.0V DC power supply with a tight tolerance of ±0.1V. It draws a typical current of 27mA, resulting in a power consumption of approximately 75mW. Using a voltage outside this specified range may damage the sensor or produce inaccurate readings.

The sensor requires a warm-up time of at least 120 seconds after power-on to stabilize its internal MEMS element and provide accurate, repeatable measurements. For best performance, allow the sensor to stabilize in the target environment before taking critical readings.

The AGS10 is a MEMS semiconductor sensor optimized for detecting ethanol, which is used as its standard test gas. It is calibrated for TVOC (Total Volatile Organic Compounds) measurement, making it suitable for general air quality assessment where ethanol and similar VOCs are indicators of pollution.

Under typical conditions of 25°C in clean air, the Asair AGS10 sensor has a lifespan exceeding 6 years. Long-term stability is a key feature of its MEMS design, although exposure to high concentrations of contaminants or extreme environmental conditions may reduce its effective service life.
