more than 1 weather board with odroid c2?

Unread postby shuckle » Wed Mar 30, 2016 3:09 am

Is it possible to connect more than 1 weather board2 to single odroid c2?

The weather bord has UV sensor, so it should be located in sun light, but then the temperature sensor shows very high values, so I would like to have another board in shadow.

Can you check the output of the ls /dev/i2c-* after loading the aml_i2c driver module?

We could use I2C-1 and I2C-2 on the C1/C2 board as this WiKi pages.

I do not have yet either the C2 nor the weather board. I wanted to check first that it works.
I'll order those. It should work I guess.

Just a confirmation that I can indeed use 2 weather bords with C1+ without issues.

Hi Shuckle,

Thanks very much for your report. I have the same issue:
"The weather bord has UV sensor, so it should be located in sun light, but then the temperature sensor shows very high values, so I would like to have another board in shadow"

That's why i have bought 2 weather boards. Would you mind to let me know who did you connect them? At the same PINs? And in that case, at which PINs exactly?

Thanks in advance!

It works like "odroid" said:

You connect the other weather station to I2C-1 pins and the other to I2C-2.

You were completely right Shuckle, both weather boards work perfectly, thanks!

One of them (temperature, humidity and pressure) is enclosed within this vaisala:

But the other weather board (uv, ir and visible light), could you advice how to enclose it in order to protect it from the rain but without avoiding the direct sunlight?

Cheers

I just put mine into a see through type plastic tube, which I happened to have around.
You can basically use enything, which passes light, bit is solid so that is blocks rain. The material you use may change the readings as it probably blocks some amount of IR and visible light. Depending how big change there is, you may need to adjust the weather board init parameters.

a word of advice the weather-board wiring length should not exceed 1 meter..1.5 at max and @1.5 it still may not work...properly
