II. Core measurement performance parameters

Oxygen range

Volume concentration: 0 - 25% O₂

Oxygen partial pressure ppO₂: 0 - 300 mbar

Accuracy and resolution

ppO₂ full-scale range accuracy: < 2% FS

O₂ concentration resolution: 0.01% O₂

ppO₂ resolution: 0.1 mbar

Built-in air pressure detection: accuracy ±5 mbar, resolution 1 mbar

Built-in temperature output: only display, resolution 0.1℃

O₂ percentage accuracy: calculated by combining oxygen partial pressure + air pressure accuracy

Response speed

Typical T90 response time: < 30 s (at normal temperature and pressure)

Preheating time: < 60 s

Default sampling period: 1 Hz (1 time/second) Service life

Continuous working life: > 5 years, no frequent calibration required

III. Electrical parameters

Power supply voltage: 4.5 - 5.5 VDC (typical 5V)

Operating current:

Continuous sampling (1Hz): < 7.5 mA

Peak instantaneous current: < 20 mA

Signal output: 3.3V TTL level UART/RS232, compatible with 5V microcontrollers, no need for op-amp conditioning, direct connection to MCU

Pins: 4 gold-plated pins, 2.54mm spacing standard PCB pads

IV. Environmental tolerance specifications Temperature

Working temperature: -30℃ ～ +60℃

Storage temperature: -30℃ ～ +60℃

Humidity: 0～99% RH (Condensation is prohibited as it can contaminate the fluorescent film)

Environmental pressure: 500～1200 mbar

Compliance: RoHS, REACH, no harmful substances, lead-free, mercury-free

V. Mechanical Dimensions

Shape: Cylindrical

Maximum diameter: 20 mm

Height: 12.5 mm

Installation method: PCB socket welding, no water washing of the entire machine (the fluorescent film is afraid of solvent erosion)

VI. Core Product Advantages

Optical principle has no electrolyte, it will not dry out, leak, or corrode, and the maintenance volume is extremely low compared to electrochemical oxygen sensors

Factory pre-calibration, ready for use on the machine, calibration once every 6 to 12 months in regular scenarios

Low power consumption, suitable for portable devices, battery-powered monitoring terminals

Built-in dual compensation for temperature and pressure, automatically correcting oxygen concentration errors caused by altitude and temperature

Resistant to CO₂ and weak acidic gas interference, suitable for chimneys, greenhouses, fermentation, and enclosed cabins

VII. Typical Application Scenarios

Environmental meteorological station, indoor air quality monitoring, incubation / agricultural greenhouse, industrial inerting protection, condensation boiler flue gas, portable respirator, laboratory biological fermentation, enclosed storage, fire oxygen deficiency warning, medical oxygen concentration monitoring
