NDIR (Non-Dispersive Infrared) sensors are highly selective and stable for CO2 detection, while MOS (Metal Oxide Semiconductor) sensors are cost-effective for detecting a broad range of VOCs but are less selective.
Gas Sensors Component Intelligence
Precision detection for volatile organic compounds, CO2, and hazardous gases.
What are Gas Sensors components?
Gas sensors detect specific atmospheric concentrations of gases. Selection depends on the target gas, required sensitivity (PPM/PPB), response time, and operating environment. Choose between NDIR for CO2, electrochemical for toxicity, or MOS for general VOC detection.
How to Choose Gas Sensors Components
Selecting the right sensor requires balancing detection limits against environmental stability and power constraints.
Detection Technology
Match the sensor type (NDIR, Electrochemical, MOS, or Catalytic) to the target gas and required selectivity.
Sensitivity & Range
Ensure the sensor's dynamic range covers your expected concentration levels without saturating.
Cross-Sensitivity
Evaluate how the sensor reacts to background gases that may cause false positives in your specific application.
Calibration Needs
Assess if the application requires factory-calibrated modules or if field calibration is necessary for long-term drift compensation.
Power Budget
Heated sensors (MOS/Catalytic) consume significantly more power than electrochemical or NDIR alternatives.
