Air measurements

Air measurements are the most common use case in the Smart Citizen Kit. These are measurements that imply measuring physical properties of the air (temperature, pressure, relative humidity), things that are in the air (gases, particulate matter) or things that travel through the air (noise, ambient light, UV-index). For this, we use a series of different sensors. These sensors can be standalone units (for instance, a CO2 sensor), or can be in sensor boards. When the data board by itself can't read the sensor directly, we need to use interface electronics to get reading from them. Below you can find a list of metrics that are already supported, but bear in mind that there are plenty of other options possible!
