The Temperature Monitor App is a Xamarin.Forms GTK Backend App running on Linux that reads temperature and humidity sensor data.
The App uploads data to Azure Table Storage. In Azure there are also a Net Core Web API that returns the data to the App, to show results in the most visual form. Using Oxyplot charts the App shows the summary of temperatures and humidities per hour each day.
Xamarin.Forms, .NET Core, Linux on server and client, sounds interesting?.
Xamarin.IoT enables developers to write and share C# code across devices, now including internet of things devices such as Raspberry Pi and Intel Edison. It works with any IoT device running Linux (most popular distributions) and integrates seamlessly with the Azure IoT Suite to connect, analyze, and secure your IoT solutions.
You can use MQTT and AMPQ with your Xamarin.IoT projects by just adding a reference to the corresponding packages.
