Weather monitor

The basic idea of the weathermon project is to obtain, record and monitor the weather at my home. All weather data sent from wireless sensors is to be stored in a database, from which different graphs are generated that can be monitored on a PC, over the Internet and on a smartphone.

System Overview

1. Weather data is measured by sensors outside and inside the house. These sensors transmit all measured values via radio link.
2. Transmitted values are received by a weather station and displayed for convenience.
3. Transmitted values are also received by a small USB device which sends them to the PC connected.
4. The PC reads received measurements and stores them in a database.
5. From this database a web server serves all measurements to clients for display.

Sensors

The sensors and the weather station come as a set from ELV:

• Outdoor sensor: ELV Funk-Kombi-Wettersensor KS300-2
• Indoor sensor: Funk-Temperatur-/Luftfeuchteaußensensor S300 TH
• Weather station: WS300

Receiver

For receiving the 868,35 MHz signals the following device from ELV is used:

• USB-Wetterdaten-Empfänger USB-WDE1
