Ndir CO2 no BMP

support for the ccs811 I2c sensor · Issue #467 · kizniche ...

2018-05-07· Human exhaled breath is around 300,000 ppmv CO2, so if you've been breathing around the sensor, it may register a high value. I'm not sure what technology this sensor uses, but NDIR CO2 sensors produce false positive measurements from high humidity. I'd check if there are any variables that may confound the measurement with this particular sensor.

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared. By measuring the amount of absorbed infrared at the appropriate frequency, the ...

Non-Dispersive Infrared, NDIR, Carbon Dioxide Sensors ...

NDIR sensors are the most reliable method for detecting carbon dioxide gas. NDIR sensors are based on infrared spectroscopy, the principal that molecules absorb specific light frequencies that are characteristic of their structure. When the frequency of the infrared light is the same as the vibration frequency of a bond, absorption occurs.
