Smart Weather Station Tutorial

Last week we gave you a little glimpse into the first stage of building a weather station - making your sensors waterproof so you can use them outside. Now we would like to provide some more insight into the weather station project by showcasing the basic functionality of measuring the temperature, humidity and light outside.


For this simple weather station prototype, we’ve put together a quick step-by-step tutorial.


Weather Station Supply List



To get started you'll need to gather the following:

  • Transparent container with a lid, large enough to hold two sensors and a master module.
  • Drinking straw
  • Drill
  • 5 mm drill bit
  • 6.5 mm drill bit
  • WunderBar temperature and humidity sensor and battery
  • WunderBar light and proximity sensor and battery
  • Master Module and battery + A USB cable
  • Caliper
  • Hot glue gun
  • Pen
  • Utility knife


The Process



Make a mark fairly close to the bottom of the plastic container. First with a pen, and then with your utility knife. This will make drilling easier. Now use the 5 mm drill bit to drill a hole in the specified spot. Even out any rough edges with the knife.




Take a straw and measure about 15-20mm from the end. Cut it diagonally. Place the straight end of the straw directly on the sensor part of the temperature and humidity sensor. Secure the straw with hot glue and then insert the battery.




Insert the sensor into the container as shown, making sure to leave enough space between the container and the sensor to access the sensor buttons. Use some hot glue around the edge of the straw to make sure that the system is sealed. Cut off the edge of the straw to give it a clean look. Now take your light and proximity sensor and create a ‘hot glue button’ on the surface.




Glue the sensor to the edge of the container as shown and insert the battery into the module. Now mark 2 spots 6 mm apart in the lower rim of the container.




Using a 6.5 mm drill bit, drill two holes in the respective places. Connect the two holes to allow the USB connector to go through and secure the connector with hot glue.




Connect the battery to the Master Module and the Master Module to the USB cable. Close the lid of the container.




Just connect the USB cable to a power supply and you are done! You have your very own prototype of the weather station.


Now, to make things even more interesting you can build your very own dashboard for the weather station. Have a look at our Weather Station project github repository to see the code and learn how to create the dashboard.
