DS4-O2-25% Industrial-grade Intelligent Oxygen Sensor For Used In Industrial Commercial Civil And Medical Fields


DS4-O2-25% Industrial-grade Intelligent Oxygen Sensor


Overview:

The DS4-O₂ intelligent oxygen sensor adopts reliable printed solid polymer electrochemical sensing technology from EC Sense, Germany. As an industrial-grade smart gas sensor, it features a compact design with high-performance microprocessors, high-precision ADC, and intelligent algorithms, enabling easy integration into IoT and other monitoring systems. It is widely used in industrial, commercial, civil, and medical fields.

Product Features:

  • Power Supply & Dimensions:
    • Wide voltage range: 3.3–12V DC (recommended 5V DC).
    • Standard industrial 4-series size: 20×16.6mm cylindrical housing with standard three-electrode pin configuration (VCC, GND, IO), facilitating new product iteration and reducing housing design costs.
  • Performance & Life Detection:
    • Intelligent self-check for sensor performance and lifespan, regularly outputting warning signals to provide fault information and advance alerts.
  • Calibration & Operation:
    • Factory-professionally gas-calibrated, with calibration data stored in the internal chip (no need for user gas calibration).
    • No preheating required; the sensor remains active without power and starts monitoring immediately after power-up.
    • User-definable encryption codes for automatic instrument identification.
    • Sleep mode support for low-power battery or IoT applications, with identity information output (gas type, range, etc.) for flexible use.
    • UART 3.3V half-duplex single-wire output directly provides gas concentration values, simplifying secondary development.
    • Supports hot-swapping, offline calibration, and one-key factory reset for safe and convenient maintenance.

Technical Parameters:

  • Detection Principle: Solid polymer electrochemical gas detection technology.
  • Repeatability: <±2%.
  • Power-Up Stabilization Time: <15 min.
  • Output Signal: UART 3.3V half-duplex single-wire, 9600 baud, 8 data bits, 1 stop bit, no parity.
  • Operating Voltage: 3.3–12V DC (recommended 5V DC).
  • Operating Current: 0.8mA @ 5V DC.
  • Peak Current: 1.1mA @ 5V DC.
  • Sleep Mode Current: 0.5mA @ 5V DC.
  • Power Consumption: ≤5mW @ 5V DC.
  • Expected Sensor Lifetime: >5 years (in air).
  • Operating Temperature Range: -40°C to +55°C.
  • Operating Humidity Range: 15–95%RH (non-condensing).
  • Operating Pressure Range: Atmospheric pressure ±10%.
  • Storage Temperature Range: 0°C to 20°C.
  • Housing Material: ABS.
  • Weight: 4.56g.
  • Packaging: Blister packaging.
