### Pre-Deployment Testing of Low-cost Gas sensors.
|
|
|
Nowadays, low-cost air quality sensors are integrated in an increasing number of measurement platforms for air quality monitoring. Calibrating these sensors to reference measurements is however challenging. These sensors typically suffer from cross-sensitivities, poor stability and sensor noise. Information about these limiting effects is often not provided by the manufacturers. Even if the information is given in a datasheet, it is often scarce and reflects sensor performance under laboratory conditions. Neglecting sensor cross-sensitivities and deployment settings usually results in poor sensor performance, frequent calibration necessity and calibration failures. This arises the need for pre-deployment sensor testing under application conditions.

### Measurement Scheduling
|
|
|
Given a route plan, a timetable, and a measurement density function. For a given mobile vehicle, regular sampling might lead to a suboptimal coverage of a city. We investigate measurement-scheduling schemes to provide optimal coverage given a route plan and a timetable. Since every measurement degrades the sensor due to involved chemical reactions, the provided problem solution assumes a limited number of measurements per sensor.
