O2OO reads sensor data from a car into a sqlite database and generates graphs of the data so you can analyze the behavior of the car. It can also retrieve the location from a GPS module and store it in the same database, then can create a Google Maps KML-file, coloring the route line with a color depending on a sensor reading.
P-rout is a tool for collecting and viewing data from the various types of a solar energy appliance called PowerRouter, manufactured by Nedap N.V. The appliance is connected to the Internet and uploads data to an HTTP server (logging1.powerrouter.com) that is owned by the manufacturer, who provides another HTTP server where customers can view their data. This project does basically the same while keeping everything on the owner's premises. It provides a data collecting HTTP server to which the PowerRouter can upload. Data is stored in a PostgreSQL database and can be reviewed on a second HTTP server. It is intended to be installed on a single-board computer with two network interfaces.
