Mobile Air Quality Monitor application for the SDS011 Sensor
This Android application is made for usage with the Nova Fitness SDS011 Air Quality Sensor which should be connected to the mobile phone using the [OTG](https://en.wikipedia.org/wiki/USB_On-The-Go) cable.
* The sensor (active) mode of work
The application puts the sensor in so-called active mode (as opposed to the query mode).
When in the active mode, the sensor sends data to the connected phone without any additional queries using the defined period (which can be continuous).
When in the query mode, the phone has to ask the sensor to sends data for each measurement. This mode is not used by aqi-sds011 application.
* The application measurement period
Application is implemented to work in two modes: - continuous - periodic
In the continuous mode, the application receives new measurement each second: - new measurement is visible on the "Current data" screen each second - multiple measurements are averaged and saved to history as defined on the "Settings" screen
In the periodic mode, the application receives new measurement as defined by the work period (minutes): - new measurement is visible on the "Current data" screen as defined by the "Settings" screen (minutes) - each measurement is saved to history immediately
