To try to reach automation in my observatory before astronomical darkness returns (Aug 22th) I want to build the meteostation indiduino.wordpress.com/2013/02/02/meteostation/

By looking at the info I have some questions about the hardware used. The links in the description is of old out of stock products.

So this is the list I have come up with so far.
  1. Arduino (Pro Micro Arduino www.kjell.com/no/produkter/elektro-og-ve...tDetailedInformation
  2. WiFi module www.kjell.com/no/produkter/elektro-og-ve...no-esp8266-14-p90745
  3. Barometric pressure sensor BMP180 looks to have replaced BMP085 ebay 201414876396
  4. DHT22 AM2302 Humidity sensor ebay 201124429073
  5. MLX90614 IR temperature sensor ebay 191869849584
  6. Cheapest solar powered LED light for daylight sensor www.clasohlson.com/no/Glasskrukke-med-so...ebelysning/36-6482-3
  7. Acryllic sheat www.clasohlson.com/no/Akrylplast/Pr341360000

If these hw selections wil work I still wonder where to mount the sensors.

I plan on mounting the IR temp sensor and the solar cell on top behind a sheat of acrylic glass.
Then have the Arduion with the WiFi module inside of the housing.
For the Barometer and humidity sensor I will mount them inside the housing to keep them dry, but have vents so they are exposed to the outside air. They will be mounted in their own compartement so they will not be affected by the heat of the arduino.

As I understand it, the humidity sensor should not be exposed to rain?

Also in the text it is mentioned that MeteoStation supports two external temperature sensors, but it does not say what sensors are used for mesuring ambient temp, is the DHT22 used for this too?

Hope someone has a little more experience with this, and can give me some tips.
I will design the housing when I know what to make :)

I have this meteostation, it's pretty awesome.
If I remember correctly, the DHT22 is used for external temperature. I had it on the outside of the box.

For the light sensor you can use the solar panel from this toy:

Thanks. that toy was cheap, so nice that it works.

One more thing. It says on the MeteoStation page that it supports two external temperature sensors.
Do you know if they are averaged out, or if it will show the temperature for each? Would be nice to keep one inside the obsy, so I can have historical graphs of the inside temp.

oh typed my reply and got wiped...
so I was saying that I do not remember if they average out or not. My meteostation box has been "recycled" and I'm planning to rebuild it for my new observatory box.

I edited, did it mess up your post?

I can order one extra and check it out, they were not to expencive.

How is pico obsy 2.0 coming along? I have not seen any updates on SGL lately.

No, it was me, I pressed the wrong button, doh :(

box updates:
It's top secret high tech space age, NASA level kind of box.... ;) Hence I have not updated the SGL forum.

Only kidding.

** Thread hi-jack warning **

Here's a preview:


Wooden frame, using proper wood techniques, I used a LOT less screws (and not a single L metal bracket), wood glue.
The side panels are aluminium composite material, the lid will also have an aluminium panel.


It's generally more compact, way lighter.
Still a work in progress, as I had to work on my race car and left the obs and anything related to it on stand-by for the last few months.

a quick video of it

Thats looking real nice, and very cleanly designed :)

I'm happy with the first season of mine. Has been bone dry all winter.
Only issues is the few things ceeping me from reaching automation.

1. no weather (Working on it)
2. Orion SSAG only calibrates if I disable two axies (It does however guide well after a minute or so)
3. If mount fails to park but driver reports parked, roof collition. (Ill ad some micro switches)
4. Due to my parking position I have set Celestron avx to 'prefer west' in meridian settings, and not to track past meridian. So I'm sure it parks on the correct side. (Will have to look into that. might be that I can find other settings that work)

So i have somethings to do this summer,

So here is the first brainstorm of the meteostation 3d printable housing.

Its 10x10x9.75 cm

The bottom part is just to keep direct rain out when its windy.
The middle part holds the sensors in the middle, slightly raised so rain wont hit them. With two holes for the wires.
The top part has a 43x43x20mm compartement for the arduino and wifi and a slanted roof for the IR sensor and Solar panel. ( I will have to make some room for mounting it with the acrylic glass covering it. )
Between the top and middle part there is room for a gasget to keep thing dry inside, and there are holes trough all the parts for 4x 50x3mm screws to hold it togheter.

Only a sketch for now, but the parts should be easily printable.

Looks decent, when are you planning to 3D print it?

I have printed the bottom part, and I am printing the middle. I also completed v1 of the design, so the top part now has room for temp and sun sensor + acrylic glass.

I will also design some gaskets to be printed i flexible material.

Ill post some pictures when im back home.

So in V1 there is no counter sunk holes for screws on the bottom part.
The mounting position for the sensors between the bottom and middle part is raised to make more room and less likely for rain to blow in when it's windy.
The top part has doubble walls for the screws and with narrower holes, so wood screws can get a better hold.
I also changed to 4x50mm screws.

On the top part I added a indent to hold a 95x95x2mm acrylic plate with room for a gasket around the edge and around the holes for 4x15mm screws.
Then a second 62x62x4mm indent to hold the solar cells and IR sensor, with some more indents to route the wires. Ending with a hole down to the arduino compartement.

I printed the bottom part and am printing the middle part. They look to be printing well. The top part will be a longer print thoug.
