Final Project: Domain Model and Information Model Specs

Here are some diagrams of my proposed Domain Model (how all the pieces of the system interact) and Information Model (what data looks like) for my final project; an air quality monitor. Because of the complexity of measuring "air quality", I have decided to focus on monitoring a single gas (Carbon Monoxide, or CO). Monitoring additional gasses and environmental readings would have similar Domain and Information models.
