That really look cool. When are you expecting to finish it?

Thanks :)

It all depends on shipping times.

I ordered all the sensors from ebay, and they all had 10 - 35 days shipping.
I have been supprized sometimes when ordering things from China and got the items closer to the 10th than the 30th day.

I will order the arduino and the wifi module, so I can set everything up and be ready to install sensors.

Btw. Does the indi driver for indoino meteostation connect to the arduino ower the network, or does it need to be connected in some other way?
I also tested the solar cell in cloud free daylight ~17:00 pointed at the sun. It was producing around 2.5v, so I think I can connect it directly to the arduino without any resistor to split the voltage.

The arduino was connected to the Pi USB port.

A very professional job!
If you are happy to share your STL files for the £D printer design, i'm very temped to have a go myself. :)

Thanks, I've uploaded it to my profile on thingiverse www.thingiverse.com/thing:2371144
Feel free to comment if you have any issues printing it.

I also edited it slightly since the last post. A hole big enough for a micro usb cable is now added. (I think I'll just drill one in mine as it's allready printed, but it should be a nice addition :) )

So now I have nearly everything I need, and I'm making some progress.

Final shopping list:
  1. 2mm tich acryllic glass www.clasohlson.com/no/Akrylplast/Pr341360000
  2. Roll of PETG printer filament
  3. Adafruit pro trinket www.kjell.com/no/produkter/elektro-og-ve...tviklingskort-p87968
  4. Serial to USB www.kjell.com/no/produkter/elektro-og-ve...b-til-seriell-p87898
  5. Solar cell lamp www.clasohlson.com/no/Solcellelampe-3-pack/36-6488-2
  6. BMP 180 Barometric Pressure sensor ebay id : 201414876396
  7. DHT22 AM2303 Temp / Humidity sensor ebay id: 171907229178
  8. MLX90614ESF-BAA IR temp sensor ebay id: 191869849584

I have to get the Usb to serial adapter tomorrow, but the rest is in house.
Compiling and uploading the firmware to the Arduino was a breeze. I did not initially realize that all the code for the induino was in the INDI driver and all the arduino does is allowing a host computer to control the IO with the firmata protocol.

The Adafruit pro trinket does not support serial commands over the usb port, so that's why I need the dongle.

Last thing that is puzzling me is that the same pin is used for the output from both the BMP085 (185) and the IR sensor? Is this correct or just to show that both should be connected to analogue input on the arduino?

See blue and purple wires on this schematics


I feel my electronics skills is lacking a bit here. It's not like the output from one goes into the other and is altered, and the outputs are in paralell, so not like they will combine, and output higher amplitude. Looks like the sensor with the strongest output will be the resulting analogue signal?

So, I'm calling this a success for the build :)

Everything is up and running except the IR sensor. I did not check everything well enough before ordering, so I got the BAA version witch is 3.3V. I connected it to the Arduino and it got hot very fast. A 20 and a 30 Ohm resistor will drop th supply voltage down to 3,3v, so I'll install the IR sensor when i can source some resistors.

I have been testing it for a while now, and sensors seam to work well. I also set up the web interface on my dev machine, and that was not hard at all. I did have to change some pins in the induinoMETEO firmware as the Adrafruit Pro trinket is using pin 2 internally. I'll go into some detail on that when I write the howto.

Also the question I had about the pressure and IR sensor using the same pins, seams to be correct. The pins are not standard analouge inputs, but SDA and SCL, witch is analouge modulated inputs.

Some pictures of the read outs and the nice Web interface for now.

Project is comming along, all sensors vorking :)

I did have to order a new IR temp sensor, as I managed to fry the first I got.
I also had to update the METEOTest and InduinoMETEO firmware. The original library for the pressure sensor only supported BMP085 and not BMP185.
The code for the IR sensor was also just crashing the program when it failed to read the sensor, making hard to debug.

The METOTest was actually for the most part crashing when a sensor failed, making it hard to debug witch semsor failed, so I have rewritten a lot of the test.

Now that all sensors are workig, I did come across a issu that wil make me redesign the top 3d printed part.
The IR sensor cannot read temperature trough the plexi / pastic glass. So the IR sensor only reports the temperature of the glass itself.

I have some ideas on how to fix it, just have to mke sure it does not make water come in to the box. (as the sensor needs to be in open air facing up

The new test firmware

Shure thing Jasem.
I'm down with the common cold now, but I might get to get a article going on Sunday.

Thanks Gonzo.
Feel free to pm me. If I'm slow to reply I might not have recovered yet :sick:
