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.
Example: Model 04-DS4-O2-25%-01 has a measurement range of 0–25%vol and a resolution of 0.1%vol.
