Introduction

Ensure safe indoor air quality with the Fermion MEMS Formaldehyde Sensor (HCHO), a high-sensitivity detector for 0-3ppm gas concentrations. Perfect for HVAC systems, air purifiers, and portable monitors, this low-power sensor delivers fast, reliable results with MEMS technology.


High Sensitivity & Fast Response

The MEMS-based sensor detects HCHO concentrations (0-3ppm) with rapid recovery times, ensuring real-time monitoring for health-critical environments.


Ultra-Low Power Consumption (＜20mA)

Designed for battery-operated devices, the sensor’s minimal power draw extends operational life in portable detectors and IoT deployments.


Compact & Easy to Integrate

At just 13×13×2.5mm, the sensor fits seamlessly into air purifiers, smart wearables, and Arduino/Raspberry Pi projects with analog voltage output.


Durable for Long-Term Use

With a 3-year lifespan and -10°C to 50°C operating range, it withstands diverse environments while avoiding interference from humidity or contaminants.


Precautions for use

  • Kindly remove the protective film before usage.
  • To prevent exposure to volatile silicon compounds vapors (such as silicone adhesive, hair gel, silicone rubber, or other locations where volatile silicon compounds are present).
  • Avoid exposure to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, etc.).
  • Prevent contamination from alkalis, alkali metal salts, and halogens.
  • Refrain from prolonged exposure to extreme environments (such as high temperatures, high humidity, high pollution).
  • Avoid contact with water, condensation, and freezing.
  • Minimize excessive vibration, impact, and dropping.
  • Please refrain from employing this module in systems that involve personal safety concerns.
  • For extended periods of non-usage, it is advisable to preheat the module for at least 24 hours.
