Fermion: Formaldehyde Sensor (Breakout, 0-3ppm MEMS HCHO Detection, Low Power)

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.
