Description

This Fermion series sensor utilizes advanced Micro-Electro-Mechanical Systems (MEMS) technology to achieve its miniature footprint and efficient performance. The MEMS structure enables low heat generation and a short preheating time, allowing for rapid response and recovery to changes in carbon monoxide concentration. The sensor operates on a 3.3V to 5V DC supply and outputs an analog voltage proportional to the detected gas level, facilitating straightforward integration into data acquisition systems.

Designed for qualitative measurement, the module is ideal for applications requiring trend monitoring and threshold-based alarming rather than precise quantitative analysis. Its construction and specified sensitivity (R0/Rs ≥ 3 in 150ppm CO) make it suitable for environments where CO presence must be detected. The sensor is rated for operation within -10°C to 60°C and 15-90% RH non-condensing humidity, ensuring functionality in a range of indoor and controlled environments.

Key Features

  • Advanced MEMS technology enables a compact, low-profile sensor design with minimal power draw.
  • High sensitivity and fast response/recovery time for timely detection of carbon monoxide gas leaks.
  • Wide operating voltage range (3.3V to 5V DC) ensures compatibility with a vast array of microcontroller platforms.
  • Robust operational lifespan rated at ≥5 years in air, offering a high-value build for long-term deployment.
  • Analog voltage output provides a simple, direct interface for system integration without complex communication protocols.
  • Pre-soldered 2.54mm pitch header pins included for quick prototyping and secure connection to breadboards or PCBs.

Applications

  • Carbon monoxide leak detection and alarm systems for residential and commercial safety.
  • Portable air quality monitors and personal CO detectors for occupational health.
  • Environmental monitoring stations for tracking CO levels in urban or industrial areas.
  • Integration into HVAC systems for indoor air quality assessment and control.
  • Educational and prototyping platforms for sensor technology and gas detection projects.

Frequently Asked Questions

What is the output signal of this CO sensor, and how do I connect it to an Arduino?

The sensor provides an analog voltage output. Connect the VCC pin to Arduino's 5V (or 3.3V), GND to GND, and the analog output pin (AO) to one of the Arduino's analog input pins (e.g., A0). You can then read the voltage value using analogRead() to monitor relative CO concentration changes.

Can this sensor provide a precise PPM reading for carbon monoxide?

No, this MEMS sensor is designed for qualitative measurement and trend monitoring, not for precise quantitative analysis. Its output indicates relative concentration changes, making it suitable for leak detection and threshold alarming rather than exact PPM reporting without specific calibration against known gas concentrations.

What is the recommended preheating time before taking stable readings?

For best performance and stable baseline readings, a preheating period is recommended. The MEMS technology enables a short preheating time, but for extended periods of non-use, it is advisable to preheat the module for at least 24 hours before relying on its readings for critical monitoring applications.

What are the key environmental conditions to avoid for sensor longevity?

To ensure the sensor's ≥5-year lifespan, avoid exposure to high concentrations of corrosive gases (H2S, SOX, Cl2, HCl), volatile silicon compounds, alkalis, alkali salts, and halogens. Also prevent contact with water, condensation, freezing, and prolonged operation in extreme temperatures, humidity, or high pollution environments.
