Description

The Asair AO-07 Oxygen Sensor Module employs a galvanic electrochemical cell principle to accurately determine oxygen concentration within a gas mixture. It generates a millivolt-level output signal proportional to the partial pressure of oxygen, requiring no external power supply for its core sensing function, which simplifies system integration. The module incorporates built-in temperature compensation circuitry to minimize measurement drift across its specified operating range, ensuring reliable performance in controlled environments.

Engineered for longevity and signal stability, the AO-07 is housed in a molded body designed for specific gas flow paths. Its performance is specified for use within a pressure range of 0.5 to 2.0 bar and in non-condensing humidity conditions. This sensor is intended as a component within a larger analyzer or control system, providing the critical sensing input for oxygen concentration regulation and safety monitoring.

Key Features

  • Self-powered galvanic cell sensor requires no external excitation voltage.
  • Advanced temperature compensation minimizes error to less than 2% O2 equivalent across 0°C to 40°C.
  • Excellent long-term signal stability and repeatability for reliable monitoring.
  • Fast response time enables quick detection of oxygen concentration changes.
  • Robust construction provides resistance to common environmental interferences.
  • Optimized performance-to-cost ratio for high-value integration into OEM equipment.
  • Specifically designed for precise measurement in medical and analytical applications.

Applications

  • Oxygen concentration sensing in medical ventilators and anesthesia machines.
  • Control system feedback component for oxygen concentrators and generators.
  • Environmental oxygen monitoring in incubators and controlled atmosphere chambers.
  • Industrial process gas analysis and oxygen safety monitoring systems.

Frequently Asked Questions

What is the output signal of the AO-07 oxygen sensor and how do I interface with it?

The AO-07 provides a linear millivolt (mV) output proportional to oxygen concentration. In ambient air (21% O2), it outputs between 9mV and 13mV. To interface, connect the sensor's output pins to a high-impedance analog input of a microcontroller or a precision instrumentation amplifier. The signal is low-level, so proper shielding and amplification may be required for long cable runs or noisy environments.

Does this sensor require an external power supply to operate?

No, the core galvanic electrochemical cell within the AO-07 is self-powered and generates its own voltage signal. However, any subsequent signal conditioning, amplification, or analog-to-digital conversion circuitry in your system will require its own power supply. The sensor itself operates passively.

What is the operating pressure range for the AO-07 sensor?

The AO-07 is designed to operate within a gas pressure range of 0.5 to 2.0 bar. Operating outside this range may damage the sensor or produce inaccurate readings. Ensure your gas sampling system regulates pressure within these limits for reliable and specified performance.

Can this sensor be used for breath-by-breath analysis in medical applications?

No, the AO-07 is not suited for breath-by-breath analysis. Its specified response time (under 15 seconds) is intended for monitoring average oxygen concentration in gas streams, such as in ventilator supply lines or oxygen concentrator outputs. It is designed for system monitoring, not for high-speed, real-time alveolar gas measurement.
