Indoor Air Quality (IAQ) index methodology - IO Frog

We added IAQ index to selected parsers to provide an overview of indoor air quality based on all available inputs including temperature, humidity, CO2 and TVOC. CO2 index. Rating Index CO2 ppm Meaning; Excellent: 1: 0 – 600: The air inside is as fresh as the air outside. Fine: 2: 600 – 1000: The air quality inside remains at harmless levels. Moderate: 3: 1000 – 1500: The air quality ...

Feasibility study of a simple IAQ index for assessing air ...

24/02/2012· The IAQ index is determined from the fractional dose of some representative common indoor air pollutants of unsatisfactory IAQ, either by taking equal importance of the pollutants as a weighting factor or weighted by the regional failure rates with respect to the corresponding air pollutants. Specifically, a database of regional IAQ assessment results of 422 air‐conditioned offices was ...

The 2021 Guide to Indoor Air Quality Monitoring (IAQ)

When it comes to IAQ sensors, most retro-fit solutions require a lot of new cabling to provide power and network from each sensor to a home network and other network hardware that makes start-up very expensive and difficult to obtain any ROI. More recently, in the past two years or so, LoRaWAN wireless network technology has reduced the cost to about 1/10th of all previous solutions. LoRaWAN ...

Calculate the Air Quality Index (IAQ, IQA) with a DSM501 ...

The Air Quality Index (IAQ) is fairly easy to determine using an Arduino (or ESP32, ESP8266) and a DSM501 sensor. The DSM501A is a detector capable of measuring the presence of fine particles in suspension in the atmosphere according to and PM10 standards. The DSM501A is a very economical sensor (about € ) which can be used as a base to build an air quality measurement …
