CHAPTER 2 STUDY GUIDE Physical Geography

These devices contain advanced sensors that can capture information via the reflection or emission of radiation from objects. Devices used for remote sensing are constructed to sense certain wavelength bands. The objects that are sensed have particular spectral signatures and one has to match the object to the sensor. The simplest and most common device employed by Geographers to carry out ...

Frequently Asked Questions about Air Emissions ... US EPA

· An example of a monitoring device that measures a surrogate pollutant is a Carbon Monoxide (CO) CEMS used to monitor the CO concentration of the effluent from a stationary combustion source that must comply with a Volatile Organic Compound (VOC) limit. In this instance, CO concentration is used as a surrogate for VOC because CO is a product of incomplete combustion and …

VOCSensor (Messung der Luftqualität)

Sensor In der MakeZeitschrift 5/20 wird eine CO2Ampel vorgestellt, die sowohl CO2 als auch VOC misst. Dort wurde für die VOCMessungen der Sensor BME680 von Bosch verwendet. Dieser ist ziemlich klein, für lowpowerAnwendungen geeignet und lässt sich über I2C/SPI ansprechen. Der Sensor kann zusätzlich zu VOCMessung außerdem die ...

Volatile organic compound Wikipedia

Volatile organic compounds (VOC) are organic chemicals that have a high vapour pressure at room vapor pressure correlates with a low boiling point, which relates to the number of the sample''s molecules in the surrounding air, a trait known as volatility.. VOCs are responsible for the odor of scents and perfumes as well as pollutants.

CO2 equivalents | Climate Change Connection

· 1 x – carbon dioxide (CO2) NOTE: Any carbon dioxide added to the atmosphere will hang around for a long time: between 300 to 1,000 years. All this time, it will be contributing to trapping heat and warming the atmosphere. 84 x – methane (CH4) – Releasing 1 kg of CH4 into the atmosphere is about equivalent to releasing 84 kg of CO 2.

Combustion and Air Quality: Emissions Monitoring Activity

· VOC sensor 2 (heavier larger hydrocarbons): Notice that the difference between the car and the truck is more apparent for this sensor, indicating that the truck is releasing a fair amount more of heavier hydrocarbons. Overall: In general, this data indicates that the truck exhaust has more emissions than the car, which makes sense, given that it is a larger vehicle with a more powerful engine ...

Accuracy, Precision, Resolution, and Sensitivity

This will dictate how the sensor responds. For example, take a sensor that is rated for 1000 units with an output voltage of 01 volts (V). This means that at 1 volt the equivalent measurement is 1000 units or 1 mV equals one unit. However the sensitivity is mV pp so it will take two units before the input detects a change. The Measurement Computing USB1608G Series Example Let’s use ...
