We've started working on a weather station project and would like to give you a glimpse into the first step of building it - making your sensors waterproof!
Once a sensor is waterproof you are able to place it anywhere outside and receive real time readings from it. The real treat about this one is that it’s simple and achievable with regular items you find around the house. We’ve put together an easy to follow step by step tutorial. So.. are you ready?
Waterproofing supply list
Before we start, here’s what you’ll need in order to make your sensor waterproof:
- A Kinder Egg
- A drill
- A 5mm drill bit
- A drinking straw
- A utility knife or scissors
- A pen
- A caliper or ruler
- A hot glue gun
Start by opening your kinder egg. Eat the chocolate and extract the little surprise container.
Next, empty the surprise container.
Use a caliper or a ruler to measure a 6 mm gap from the rim of the surprise container.
Use a pen and then your utility knife to mark the spot and drill a hole at the specified spot. Careful not to hurt yourself!
Next, take a straw and measure around 15-20 mm from the edge of it. Cut the straw diagonally.
Take your humidity and temperature sensor and place the straight side of your straw on top of the sensor.
Secure the straw with hot glue. You can simply place two drops on opposite sides of the straw then go around it to secure it in place.
Next, insert the straw into the hole as exhibited.
You may need to make some adjustments to the length of the straw... careful not to cut your fingers.
Make sure that the sensor's button is facing upwards and that the battery holder is accessible.
Secure the position of the sensor in the plastic case with the help of hot glue.
Next, apply some hot glue around the straw to make sure the system is well sealed.
Cut off the top of the straw- just to give it a cleaner look.
And... you are done!
Now drop the box into a glass of water to test it.
You are able to use the same technique for the Master Module with the help of an old Film canister as well as for the light and proximity sensor with the help of a tic-tac box.
And this is how you make your sensor waterproof!
Stay tuned for the next steps to create your very own weather station.
