Pocket Weather Station

Description

Hi, in this tutorial, you will learn to build a pocket weather station using an Arduino Nano board. It will be a compact device that you can carry anywhere around, right in your pocket and will be capable of displaying the live temperature and humidity on the OLED display present on it. This is a great self-care device as you will always know when to take an umbrella out with you, both for the rain and the scorching heat!

Hi, in this tutorial, you will learn to build a pocket weather station using an Arduino Nano board. It will be a compact device that you can carry anywhere around, right in your pocket and will be capable of displaying the live temperature and humidity on the OLED display present on it. This is a great self-care device as you will always know when to take an umbrella out with you, both for the rain and the scorching heat!

You can carry it around as it has an inbuilt rechargeable 160mAh lipo battery. It is a really great project for learning and is also really fun to make. It might come out really handy sometimes.

When we start experimenting with a DHT11 temperature sensor, what we do is take a breadboard and some jumper wires and some kind of a display and start experimenting with some random code. Instead of doing that, I gave the DHT11 module a professional and comfortable home and made a much more realistic project for learning.

Gather Components
The first thing to do when beginning with any project is gathering the required components. The required components for this project are as follows:

1.1 Components:
- Arduino Nano with Cable
- DHT11 Temperature Sensor Module
- 0.96" OLED Display
- TP4056 Battery Charging Module
- Small Battery (I used 160mAh lipo battery)
- Slide Switch
1.2 Tools (according to need / optional):
- Soldering Iron
- Jumper Wires
- Hot Glue Gun
- 3D Printer (for enclosure - highly optional)
I always prefer Quartz Components to buy all kinds of electronic components and tools!

Gather all the required stuff and move ahead to the next step!

Stacking Components

Now we need to plan the position of all the components inside the enclosure. I wanted to keep the device as thin as possible so it is actually convenient to carry in a pocket. Thus I spread all the components out and did not go with a multiple component-layer structure as that would decrease the X and Y dimensions of the device but eventually increase the Z dimension which is nothing but the thickness of the device!

You can refer to the image attached above to check how I have stacked the components inside my pocket weather station or you can also come up with your own unique and creative ideas 💡 of stacking the components in ways that reduce the size of the device even further!

After you are done planning your preferred arrangement, head straight over to the next step!

Schematic

Now we need to draft out a schematic for our pocket weather station. The schematic for this project is very simple as there are very few modules and have to be just connected together without the need for any external modifiers. I have attached the schematic diagram above, as an image. You can refer to it if required.

We need to connect the battery to the battery charging module and the output of the battery charging module to the Arduino Nano board. I have used an Arduino Nano board because of its size which is perfect and preferable for this project!

Next, connect the temperature sensor module and the OLED display to the Arduino board.

After completing the schematic, move ahead to the next step.
