Fermion: MEMS Nitrogen Dioxide NO2 Gas Detection Sensor

What Is This Sensor?

• A MEMS-based gas sensor designed to detect Nitrogen Dioxide (NO) concentration in air.

• Uses Micro-Electro-Mechanical Systems (MEMS) technology for compact size, low power, and high sensitivity.

• Commonly used in air quality monitoring and environmental sensing systems.

Key Features

• Target Gas: Nitrogen Dioxide (NO)

• High Sensitivity: Detects very low concentrations (ppm level)

• Low Power Consumption: Typically <20 mA

• Compact Size: Around 13 13 2.5 mm

• Fast Response & Recovery: Suitable for real-time monitoring

• Analog Output: Provides voltage proportional to gas concentra Specifications

  How It Works

  • The MEMS sensing element reacts chemically with NO gas.

  • This interaction changes the sensor's internal resistance.

  • The onboard circuit converts this change into an analog voltage signal.roller ADC and converted into gas concentration (ppm).

   

  Applications

  • Air quality monitoring systems

  • Smart city pollution monitoring

  • Industrial safety (toxic gas detection)

  • Automotive emission monitoring

  • IoT environmental sensing projects

   

  Important Notes

  • Calibration Required: For accurate ppm readings, calibration with known NO concentrations is needed.

  • Cross Sensitivity: May respond slightly to other gases (like NO, H depending on variant).

  • Environmental Sensitivity: Temperature and humidity can affect readings.

  • Not for Critical Safety Systems: Not recommended for life-critical applications.

  •
