In this chapter, we will make an outdoor weather station that is accessible over the Internet, which will allow remote monitoring and recording of the weather conditions.

To do this, we will have a look at a new skill that will allow us to take some existing sensors and adapt them for use in our project—reverse engineering. This is essentially the process of taking a part of an existing product and deriving the communication method between it and the rest of the product, so that you can replace either a specific part or a whole product.

We will also take a quick look at how to use the Pi as a web server and the method used to develop and deploy a Python web application.
