This is a tutorial on building a Compost Temperature monitoring system. It details how to build a web connected wireless sensor network and shows one possible way it could be constructed.
A Medium level of knowledge and skills are required. Basic knowledge of soldering and breadboarding will be very useful. I will assume that you know enough Arduino code to understand what a Function is, how a Library is useful, and why Serial Communication is important. And you will need to know enough electronics to understand what I mean with terms like Voltage, Current, Resistance, etc. A (very) basic knowledge of how radio works would also be useful for understanding the concepts, but not essential for following along. This is not advanced by any means and I will attempt to always reference materials that will cover these concepts in greater detail.
This tutorial is not about building a polished final product. I am going to assume that you are accompanied by some basic fabrication skills and are capable of doing some problem solving in this area. I will show an example of my project at the end, but I will not be talking extensively on housing design or fabrication. This will be purely about the code and electronics to get up and running with the various communication types, sensors, and data storage. That being said, by the end of this tutorial you will have a web connected sensor network working on your breadboard. Putting it into a housing will be easy after that.
