Instant wind data is received from the sensor by the Raspberry Pi via radio reciever and updates in real time.
<p>
The Barometric data actually comes from the Davis console device indirectly via the Internet and has a 15 minute delay. There will soon be a barometric sensor connected locally to fix this.

Instant wind data is received from the sensor by the Raspberry Pi via radio reciever and updates in real time.
<p>
The Barometric data actually comes from the Davis console device indirectly via the Internet and has a 15 minute delay. There will soon be a barometric sensor connected locally to fix this.
