AirMonitor
AirMonitor is an ESP8266 based CO2, TVOC, temperature and humidity data logger.
The device can be configured to be an access point or it can be connected to another network. The data can be viewed using the build in html user interface. It does not require an Internet connection or any other applications.
Note: The CO2 and TVOC will drift in the long run. To get better results use a more expensive sensor for these measurements.
Hardware
- ESP8266 development board
