ZE29A-C2H5OH High-selectivity Ethanol Gas Sensor For Detecting Ethanol Vapor In Indoor/Outdoor Air
1. Product Overview:
The ZE29A-C2H5OH is a high-selectivity ethanol (C₂H₅OH) gas sensor based on semiconductor (metal oxide) sensing technology. It is designed for detecting ethanol vapor in indoor/outdoor air, with applications in breath alcohol testers, food processing quality control, fuel leak detection, and indoor air quality (IAQ) monitoring. The sensor features low power consumption, fast response, and stable output, supporting both analog and digital signal integration for flexible system design.
2. Application Notes:
| Parameter Category | Parameter Name | Specification | Unit | Remarks |
|---|---|---|---|---|
| Target Gas & Sensing Principle | Target Gas | Ethanol (C₂H₅OH) Vapor | - | Minimal cross-sensitivity to methane, propane, benzene, and common VOCs |
| Sensing Principle | Semiconductor (Metal Oxide: SnO₂-based) | - | Resistance changes with ethanol concentration; heated by internal micro-heater | |
| Measurement Performance | Detection Range | 10 ~ 1000 ppm (Standard); 5 ~ 2000 ppm (Custom) | ppm | 10~1000 ppm for breath alcohol (BAC correlation: ~0.02~0.2 mg/L); custom range for industrial use |
| Resolution | ≤ 1 ppm (10~1000 ppm range) | ppm | Minimum detectable concentration change | |
| Accuracy | ±5% FS (25℃, 1 atm, 50% RH); ±10% FS (-10℃/+50℃) | - | FS = Full Scale; tested with 100 ppm ethanol standard gas | |
| Response Time (T90) | ≤ 10 | Seconds | Time to reach 90% of stable output (at 50 ppm ethanol) | |
| Recovery Time (T10) | ≤ 30 | Seconds | Time to drop to 10% of stable output (after removing ethanol) | |
| Electrical Characteristics | Power Supply Voltage | 5.0 ± 0.2 V DC (Main); 3.3 ± 0.1 V DC (Heater) | V (DC) | Heater voltage must be stable (ripple ≤ 50 mV) to avoid drift |
| Operating Current | Total: ≤ 80 mA (Main: ≤ 20 mA; Heater: ≤ 60 mA) | mA | Heater current peaks at startup (≤ 100 mA for 30s); stabilize afterward | |
| Output Signal Type | Option 1: Analog (0.1 ~ 0.9 V DC, linear with concentration); Option 2: Digital (UART, 9600 bps, 8N1) | - | Analog for simple circuits; UART for data logging/remote monitoring | |
| Zero Drift (Monthly) | ≤ 2% FS | - | In clean air (ethanol < 1 ppm); drift increases in high humidity (>80% RH) | |
| Environmental Adaptability | Operating Temperature Range | -10 ~ 55 | ℃ | Optimal: 15 ~ 40℃ (minimal temperature interference) |
| Storage Temperature Range | -20 ~ 60 | ℃ | Store in dry, ethanol-free environment; avoid dust/condensation | |
| Operating Humidity Range | 10 ~ 90 | % RH | Non-condensing; condensation damages the sensing film | |
| Atmospheric Pressure Range | 86 ~ 106 | kPa | Suitable for altitudes ≤ 2000 meters; performance degrades above 3000 meters | |
| Mechanical & Physical Specs | Package Type | DIP-6 (Dual In-line Package, 6 pins) | - | Easy to prototype; compatible with standard breadboards |
| Overall Dimensions (L×W×H) | 22.0 × 18.0 × 7.5 mm | mm | Excludes pin length (pins: 5.0 mm length, 0.6 mm diameter) | |
| Weight | ≤ 10 g | g | Net weight (no cables or accessories) | |
| Gas Intake Mode | Diffusion (Passive) | - | No external pump needed; ensure ≥ 3 mm clearance around the sensor for airflow | |
| Lifespan & Maintenance | Typical Operational Lifespan | ≥ 3 | Years | Under normal use (no exposure to ethanol > 2×FS, no corrosive gases) |
| Calibration Interval | 12 ~ 24 | Months | Recommended for high-precision applications (use NIST-traceable ethanol calibration gas: 100 ppm) | |
| Preheating Time | 3 ~ 5 |
