Access to Gill Windsonic Anemometer
|
||
|
|
===================================
|
||
|
|
|
||
|
|
We use the second serial port to receive data from the Gill Windsonic
|
||
|
|
ultrasonic anemometer:

|
||
|
|
|
||
|
|
The Windsonic needs to be set up properly to send data periodically
|
||
|
|
(every two seconds in my setup) in the Polar Format with fixed CSV
|
||
|
|
sizes at 9600 baud.
|
||
|
|
|
||
|
|
I used a MAX3323EEPE to translate the RS232 from Windsonic to Merkurboard
|
||
|
|
3.3V levels.
|
||
|
|
|
||
|
|
The complete setup is driven by a 12V solar charged acid battery. The
|
||
|
|
/power_supply ressource measures the voltage level on the input.
|
||
|
|
The voltage is measured by a simple 1M/100k voltage divider directly
|
||
|
|
connected to the merkurboard.
|
||
|
|
|
||
|
|
A small DC/DC converter is used to power the merkurboard.
|
||
|
|
|
||
|
|
Next step maybe put the merkurboard and MAX3323 in the Windsonic's case
|
||
|
|
to have the first open source ipv6 addressable windsonic on earth ;-)
