Build an Arduino BLE-Enabled Indoor Air Quality Monitor ...

The iAQ-Core indoor air quality sensor module is the heart of the project and is used to provide CO 2 and total volatile organic compounds (TVOC) equivalent predictions. The sensing range from the datasheet is as follows: 450-2000 ppm CO 2 equivalents and 125-600 ppb TVOC equivalents. "Equivalents" are somewhat vague units and are not defined as well as I would have liked. From …
