ZE07-CO Carbon Monoxide Gas Sensor For Residential & Commercial CO Alarms Portable Occupational Safety Devices

1. Product Overview:

The ZE07-CO is a cost-effective, industrial-grade carbon monoxide (CO) gas sensor designed for reliable detection of toxic CO concentrations in indoor, outdoor, and industrial environments. Leveraging advanced electrochemical sensing technology, it delivers high accuracy, stable performance, and fast response—critical for applications where CO leaks (from fuel combustion, industrial processes, or confined spaces) pose risks to human health or safety. With a compact form factor and flexible output options, it is widely compatible with portable detectors, fixed monitoring systems, and smart home safety devices, making it suitable for both professional and consumer use cases.

2. Core Features:

• High Sensitivity to Toxic CO Levels: Optimized for detecting low-to-moderate CO concentrations (0~1000 ppm), covering critical safety thresholds (e.g., OSHA’s 35 ppm 8-hour TWA and 200 ppm 1-hour STEL), ensuring early warning of hazardous exposure.
• Excellent Selectivity & Anti-Interference: Adopts a three-electrode electrochemical structure that minimizes cross-sensitivity to common interfering gases (e.g., H₂, CH₄, ethanol, CO₂), avoiding false alarms in complex environments.
• Fast Response & Recovery: Features a T90 response time of ≤ 30 seconds and T10 recovery time of ≤ 60 seconds, enabling rapid detection of sudden CO spikes (e.g., from faulty heaters or blocked vents) and quick return to baseline after danger passes.
• Dual Output Modes for Flexibility: Supports both analog output (0~5 V DC / 4~20 mA DC) and digital output (UART), compatible with microcontrollers (Arduino, ESP32), PLCs, and data acquisition systems—simplifying integration into diverse devices.
• Low Power Consumption: Operates on 5 V DC with a typical working current of ≤ 30 mA, making it ideal for battery-powered portable detectors (e.g., handheld CO alarms) and low-power IoT monitoring systems.
• Wide Environmental Adaptability: Functions reliably in temperatures from -10℃ to 50℃ and humidity from 15% to 90% RH (non-condensing), suitable for harsh industrial sites, residential areas, and vehicle cabins.
• Long Lifespan & Low Drift: Boasts a typical operational lifespan of ≥ 2 years (under continuous use in clean air) and annual signal drift of ≤ 2% FS, reducing maintenance costs and ensuring long-term measurement accuracy.
• Easy Installation & Calibration: Compact design (standard dimensions: 45×35×18 mm) and diffusion-type gas intake allow for simple mounting; factory pre-calibration eliminates the need for on-site adjustment before initial use.

3. Typical Applications:

• Residential & Commercial CO Alarms: Integrated into standalone smart home CO detectors or combined smoke/CO alarms to protect households, apartments, and offices from CO leaks caused by gas stoves, water heaters, fireplaces, or blocked chimneys.
• Portable Occupational Safety Devices: Used in handheld detectors for workers in high-risk industries (e.g., mining, construction, automotive repair) to monitor personal CO exposure in confined spaces (e.g., underground mines, vehicle garages) or near fuel-burning equipment.
• Industrial Process Monitoring: Deployed in factories (e.g., steel mills, power plants, chemical refineries) to track CO levels in combustion processes (e.g., boiler operations) or waste gas emissions, ensuring compliance with environmental regulations and worker safety standards.
• Vehicle Cabin Monitoring: Integrated into automotive or marine systems (e.g., RVs, boats) to detect CO buildup from exhaust leaks or malfunctioning heaters, triggering alerts to protect passengers and crew.
• Indoor Air Quality (IAQ) Systems: Part of commercial IAQ monitors for shopping malls, hotels, and office buildings to continuously measure CO concentrations (a key indicator of incomplete combustion) and optimize ventilation systems.
• Fire Emergency Response: Used in portable detectors by firefighters or emergency personnel to assess CO levels in fire-damaged buildings, ensuring safe entry and protecting against post-fire CO poisoning.
