Description

The ZE03-CO module utilizes a mature three-electrode electrochemical sensor cell paired with a high-performance microprocessor. This design ensures stable, accurate readings of carbon monoxide concentrations by actively compensating for ambient temperature variations via its integrated temperature sensor.

Its dual-output architecture provides both a digital UART interface for direct communication with host systems and an analog voltage signal proportional to gas concentration, simplifying calibration and shortening development cycles. The module is engineered for reliability in various environmental conditions, making it a core component for professional gas detection solutions.

Key Features

  • High-sensitivity electrochemical detection cell specifically for Carbon Monoxide (CO)
  • Microprocessor-controlled signal conditioning and temperature compensation
  • Dual output mode: TTL-level UART (Modbus protocol) and 0-3V analog voltage
  • Very low operating current, typically under 5mA, for battery-powered applications
  • Stable performance across a 30% to 70% relative humidity range
  • Designed for a 2-year operational life under normal use conditions
  • Robust anti-interference circuitry for reliable readings in electrically noisy environments
  • Compact, board-level module for easy integration into OEM equipment

Applications

  • Fixed carbon monoxide detectors for industrial safety and HVAC monitoring
  • Portable personal safety gas monitors and handheld detectors
  • Air quality monitoring systems in parking garages, tunnels, and workshops
  • Integration into building automation and smart home safety control panels
  • OEM gas detection equipment for fire prevention and environmental safety

Frequently Asked Questions

What is the output interface of the Winsen ZE03-CO module?

The module provides two simultaneous outputs: a digital UART (TTL-level) interface using a Modbus protocol for direct communication with microcontrollers or computers, and an analog voltage output (typically 0-3V) proportional to the CO concentration. This dual-output design offers flexibility for both digital data acquisition and simple analog threshold detection.

What is the operating voltage range and power consumption?

The ZE03-CO operates from a DC power supply between 4V and 9V. It is designed for low-power applications, with a typical operating current of less than 5 mA, making it suitable for battery-powered portable devices and energy-efficient continuous monitoring systems.

How do I calibrate the sensor, and what is its lifespan?

Calibration typically requires a known concentration of CO calibration gas and is performed via commands sent over the UART interface. The integrated microprocessor facilitates this process. The electrochemical sensor cell has a typical operational lifespan of approximately 2 years under normal environmental conditions (20-50°C, 30-70% RH), after which sensor sensitivity may degrade.

Can this module detect gases other than Carbon Monoxide?

No, the ZE03-CO variant is specifically calibrated for Carbon Monoxide (CO) detection. The ZE03 platform can be configured with different electrochemical sensor cells to target other gases like O2, NH3, H2S, NO2, O3, SO2, or CL2, but each model (e.g., ZE03-CO) is dedicated to a single target gas.
