DS4-HCHO-100 Electrochemical Gas Sensor Self-identification Capability For System Integration

DS4-HCHO-100 Electrochemical Gas Sensor

Detection Principle:

Adopts EC Sense (Germany) solid polymer electrochemical detection technology based on electrochemical catalytic reaction. The sensor consists of three electrodes in contact with a solid electrolyte, typically made of high-surface-area noble metals and other materials. Gas diffuses through a porous membrane to the working electrode, where oxidation or reduction reactions occur on the electrode surface, generating a current signal proportional to the gas concentration.

Features:

• Wide Power Supply Range: Operates within 3.3V–12V DC (recommended 5V DC).
• Broad Temperature Range: Functions normally at -40°C to +55°C without temperature compensation.
• Stable Performance: Exhibits excellent long-term zero-point stability, anti-poisoning capability, and long service life.
• Rapid Response: Quickly captures gas concentration changes for real-time monitoring.
• Good Linearity: Output signal shows linearity with gas concentration within the detection range.
• Low Power Consumption: Low-power design with sleep mode, suitable for battery-powered IoT devices.
• Compact Size: Standard 4-series industrial size (20mm diameter × 16.6mm height, excluding pins), weighing <6g for easy integration.
• User-Friendly: Factory-precalibrated (no user calibration needed); self-identifies gas type and range; supports user-defined encryption codes to prevent misinsertion of other sensors.

Performance Parameters:

• Measurement Range: 0–100 ppm
• Resolution: 0.1 ppm
• Maximum Overload: 200 ppm
• Sensitivity: 35±20 nA/ppm
• Response Time: T50 < 20s, T90 < 120s

Physical Parameters:

• Dimensions: 20mm (diameter) × 16.6mm (excluding pins)
• Weight: <6g

Environmental Parameters:

• Operating Temperature Range: -40°C to +55°C
