Description

The Asair AOX4000 oxygen sensor operates on the principle of fluorescence quenching, where oxygen molecules quench the fluorescence of a sensitive layer, providing a stable and accurate measurement of oxygen partial pressure. This method offers significant advantages over traditional electrochemical sensors, including a longer operational lifespan, no drift over time, and minimal power consumption.

The module incorporates a built-in atmospheric pressure sensor and advanced temperature compensation algorithms, enabling it to output fully calibrated values for oxygen partial pressure, oxygen concentration (0-25%), and ambient air pressure (500-1200 mbar) directly. This integrated design simplifies system integration, requiring no additional compensation hardware for reliable performance across a wide range of environmental conditions.

Key Features

  • High-precision oxygen sensing based on fluorescence quenching technology.
  • Integrated temperature and pressure compensation for accurate, calibrated outputs.
  • Digital output provides oxygen partial pressure, concentration, and atmospheric pressure values.

Frequently Asked Questions

What is the operating voltage range for the AOX4000 sensor?

The Asair AOX4000 requires a regulated DC supply voltage between 4.75V and 5.25V. It is designed for standard 5V logic systems, making it directly compatible with platforms like Arduino Uno, Raspberry Pi (with level shifting), and other 5V microcontrollers. Ensure your power source can provide the peak current of up to 32mA.

How does the fluorescence quenching principle work, and what are its benefits?

The sensor contains a luminescent material whose fluorescence is quenched (reduced) in the presence of oxygen molecules. The degree of quenching is directly related to the oxygen partial pressure. This optical method provides a long lifespan (as it doesn't consume the sensing element), excellent stability with minimal drift, and fast response times compared to traditional electrochemical sensors.

What data does the sensor output, and how is it communicated?

The AOX4000 provides fully calibrated digital outputs for three key parameters: oxygen partial pressure, oxygen concentration (0-25%), and ambient atmospheric pressure (500-1200 mbar). The specific digital communication protocol (e.g., I2C, UART) should be confirmed from the official Asair datasheet for proper wiring and data reading into your microcontroller.

Does this sensor require external temperature compensation?

No, the AOX4000 features built-in temperature compensation. The integrated compensation system automatically corrects for ambient temperature variations, ensuring accurate oxygen readings across its operating range without the need for any additional external hardware or complex calibration routines from the user.
