Description

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:

  1. Preheating Requirement: The sensor must be preheated for 3~5 minutes after power-on to ensure accurate readings. Do not take measurements during preheating.
  2. Cross-Sensitivity Avoidance: Avoid exposure to high concentrations of isopropanol, methanol, or these may cause false positive readings. For critical applications, add a gas filter (e.g., activated carbon) to enhance selectivity.
  3. Mounting Guidelines: Mount the sensor in a location with good airflow (away from dead corners). Do not mount near heat sources (e.g., resistors, LEDs) or moisture-prone areas (e.g., sinks, vents).
  4. Heater Stability: Use a regulated power supply for the heater (voltage ripple ≤ 50 mV). Unstable heater voltage leads to severe output drift.
  5. Warranty: The sensor comes with a 12-month warranty from the date of purchase. Warranty is void if damaged by condensation, corrosive gases, or improper voltage.

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
