This is a hardware+software project. A wind sensor is connected to a Raspberry Pi via the GPIO interface. The Pi collects measurements and uploads them to a web server, which stores them in a MySQL database. The server shows various statistics, such as wind speed over time, average, maximum and a histogram.
- DHT22 type sensor for temperature and humidity.
- MCP3008 analog/digital converter for custom inputs, e.g. voltage.
- Digital switches, e.g. "door open" detection and pilot counter.
