Description

The Winsen ZE03-CL2 employs a mature three-electrode electrochemical sensing principle paired with an onboard microprocessor for precise monitoring of chlorine gas concentration. Its design integrates automatic temperature compensation to ensure accuracy across varying environmental conditions from -20°C to 50°C.

This module provides both digital UART communication and a linear analog voltage output, offering flexibility for direct analog reading or digital data logging and calibration. Its industrial-grade construction and low power profile make it suitable for continuous monitoring in fixed installations and portable detection equipment.

Key Features

  • High-sensitivity electrochemical sensor for reliable chlorine gas detection.
  • Simultaneous UART (3V TTL) and 0-2V analog outputs for versatile system integration.
  • On-chip temperature compensation ensures measurement stability across operating conditions.
  • Optimized performance-to-cost ratio with a two-year sensor life expectancy.
  • Robust anti-interference circuitry for stable operation in electrically noisy environments.
  • Wide operating voltage range (4-9V DC) compatible with common power supplies.
  • Compact, board-level module design for easy embedding into host systems.

Applications

  • Industrial safety monitoring in water treatment and chemical processing plants.
  • HVAC and indoor air quality control systems in swimming pools and recreational facilities.
  • Portable gas leak detectors and fixed wall-mounted alarms for chlorine.
  • Environmental monitoring stations and research equipment for atmospheric studies.
  • Process control and automation in bleaching and disinfection operations.

Frequently Asked Questions

What is the output interface of the ZE03-CL2 module and how do I connect it?

The module provides both a UART (TTL 3V logic) serial interface and a linear analog voltage output (0-2V corresponding to 0-20 ppm). For UART, connect the module's TX/RX pins to your microcontroller's UART pins. For analog, read the output pin with an ADC. Ensure the module's VCC is supplied with 4-9V DC and GND is common.

What is the sensor's lifespan and does it require calibration?

The electrochemical sensor element has a typical lifespan of two years under normal operating conditions. Periodic calibration is recommended for critical applications to maintain accuracy. The analog output can be zeroed and spanned using known concentration calibration gases, while the UART output provides pre-processed digital concentration values.

Can this sensor operate with 5V or 3.3V microcontroller logic?

Yes. The module's operating voltage range is 4-9V DC, independent of the logic levels. Its UART output is fixed at 3V TTL levels, which is generally compatible with both 5V and 3.3V microcontroller inputs. The analog output is a voltage signal that can be read by any ADC within its 0-2V range.

What environmental conditions can this sensor operate in?

The sensor is rated for operation from -20°C to 50°C and 15% to 90% relative humidity (non-condensing). It includes built-in temperature compensation. For storage, maintain conditions between 20-25°C and 30-70% RH to maximize sensor life.
