1. Ik like your project and would like to build it myself..

2. Please create a detailed construction document for this weather station project (including lots of pics)! 🙂

   • What a great idea! Will do.

3. Dear John,

   How can I run on Raspberry Pi? Do you have a Python code ?

   Thanks

   • Yes, you can use WeatherRack on the Raspberry Pi using Python. Look at the Python library mentioned in this article.

4. Where did you purchase the lightning detector?

   • Embedded Adventures. Excellent quality and delivery. Works like a champ.

     John

   • Of course, I found one right after posting the question. https://www.embeddedadventures.com/as3935_lightning_sensor_module_mod-1016.html

5. Thank you!

6. I just purchased the weatherpiaudrino and the weatherrack sensors. I am trying to get those two things working with my pi without anything else and then I will start to add things as I go along.

   Do I need to solder the DS3231 to the board? Do I need to add anything else to the board for this to work?

   I was going to start with the software you have graciously provided here: https://github.com/switchdoclabs/WeatherPi

   Thanks in advance
   Hans

   • Hans,

     You can put in a socket and plug the DS3231 into the board. If you solder it make sure that you have it oriented correctly!

     There is nothing else REQUIRED to make it work. If you are using a Pi, you will get much better wind vane accuracy by adding an ADS1015 (from Adafruit) onto the board.

     Best regards,

7. I may have answered my question above, I was able to get the BMP180 barometer temp and altitude readings, but not the wind speed/direction or rain information. When I run SDL_Pi_Weather_80422Test.py I get all zero’s. I saw that there were gpio pin numbers in there anenometerPin = 23 and rainPin = 24, but I don’t see those gpio’s in the wiring diagram you have above for the pi. They seem to be connected to GPIO 15 and 18? Can you help me out here? Thanks!

   • My guess is you have confused the two numbering systems for GPIOs. The way that the Raspberry Pi designers did this is a source of confusion for many people. Check out this page to understand it.

8. Hi SDL,

   I have all the devices connected but when i run the test script i get this:

   Help appreciated.

   • Hi Luke,

     We suspect that you have a board that has a different I2C address for the AT24C32 EEPROM.

     run ‘sudo i2cdetect -y 1’

     0x68 is the DS3231 and 0x56 is the AT24C32. Note that on some of the new revision boards the AT24C32 address is 0x57. Change the address of the AT24C32 to 0x57 if this is the case.

     SDL

     • Hi SDL,

       Thanks for the reply.

       Not sure i follow. My AT24C32 looks to be at 0x57. Do you mean to change it to 0x56?

9. All good, i changed it to 0x56 and it appears to be working – thanks

   • Totally Bizarre. And the I2C is reporting 57. Very strange.

     SDL

10. Oh sorry no – i changed it from 0x56 to 0x57 and it now works. It’s not picking up wind speed but i haven’t looked into that yet. Cheers

11. Hmmm so i have looked into it and can’t find anything wrong with the Anemometer. I have the Spark Fun weather sensors. The Anemometer is patched via the Wind Vane which is connected to JP2. Readings are always 0 even with movement.

    Any ideas?

    Thanks

    Luke

    • Verify that the anemometer is closing. If it is, then you probably have a wiring error. Check which gpio you have connected to the anemometer and that it matches the code.

12. hi, i have a problem, i have the WeatherRack Weather Sensors and the WeatherPiArduino Weather board. I try to run SDL_Pi_Weather_80422Test.py. I downloaded these drivers https://github.com/switchdoclabs/SDL_Pi_Weather_80422 but when I try to run this error message

    pi@raspberrypi ~/SDL_Pi_Weather_80422-master $ sudo python SDL_Pi_Weather_80422Test.py

    There are some tutorial to make the whole process ? or am I doing wrong ?

    Thanks. Gracias

    • Did you install the entire github repository?

      Best,
