Volatile organic compounds, or VOCs are organic chemical compounds whose composition makes it possible for them to evaporate under normal indoor atmospheric conditions of temperature and pressure 3. This is the general definition of VOCs that is used in the scientific literature, and is consistent with the definition used for indoor air quality.
VOC testing methods TO-15, TO-17 and ASTM D5504. The EPA’s Method TO-15 outlines proper VOC testing by collecting air in a specially-prepared stainless steel vacuum canister. Air is drawn into the canister through a flow controller for as little as an hour or as long as two days. Then, the canister is sent for laboratory analysis.
A CO2 sensor is designed to control the ventilation rate in occupied spaces. People are the principal source of CO2 in indoor air. Whereas outside air carbon dioxide levels tend to be relatively low and constant, an indoor CO2 measurement can be used to determine whether a room or building is occupied.
Now we go back to the datasheet and find this instructions to get de sensor data. First we need to send the command Initi_air_quality 0x2003 then we can send the command Measure_air_quality 0x2008. For 15 seconds the response will be 400 for CO2 and zero for TVOC. IMPORTANT: put in comment ou remove the code that we did in the last step.
The indoor air quality index plays an important role on our health. Canadians spend more time indoors than outdoors. We are at schools, workplaces, stores, and home. Because we spend so much time indoors, we have created Indoor Air Quality Index to become more concerned about the relationship between Indoor Air Quality and health.
