ZE07-H2 Hydrogen Gas Sensor For Portable Hydrogen Leak Detectors Fixed Hydrogen Monitoring Systems
1. Product Overview:
The ZE07-H2 is a high-performance, electrochemical-type hydrogen (H₂) gas sensor designed for accurate detection of hydrogen gas concentrations in air. It features small size, low power consumption, and stable output, making it suitable for various industrial, commercial, and residential hydrogen leak monitoring scenarios.
2. Key Features:
- Electrochemical Sensing Principle: Offers high selectivity to H₂, minimizing interference from common gases (e.g., CO, CH₄, ethanol).
- Wide Detection Range: Covers typical hydrogen leak and monitoring needs (see "Electrical Specifications" for details).
- Low Power Consumption: Suitable for battery-powered or low-power embedded systems.
- Fast Response & Recovery: Rapidly detects H₂ concentration changes and returns to baseline quickly after gas removal.
- Analog Output: Provides linear analog voltage output proportional to H₂ concentration for easy signal acquisition.
- Compact Design: Small form factor enables integration into portable detectors or compact monitoring devices.
- Long Service Life: Industrial-grade components ensure stable performance and extended operational lifespan.
3. Installation & Usage Notes:
- Gas Exposure: Avoid prolonged exposure to H₂ concentrations exceeding the full-scale (FS) range, as this may damage the sensor and shorten its service life.
- Environmental Protection: Do not install the sensor in areas with condensation, heavy dust, or corrosive gases (e.g., Cl₂, H₂S), as these will interfere with performance.
- Calibration: Perform regular calibration (recommended every 6–12 months) using a standard H₂ gas source to maintain detection accuracy.
- Signal Processing: The analog output requires a low-pass filter (e.g., 100 Hz RC filter) to reduce noise; for digital UART output, ensure correct baud rate (typically 9600 bps) and communication protocol matching.
- Power Supply: Use a stable DC power supply to avoid voltage fluctuations affecting the sensor’s output stability.
