# Weather Station

This repository contains the code and instructions required to build a simple

weather station powered by an esp32 microcontroller, a DHT22 temperature sensor

and an infrared receiver.

It uses esp-idf framework for managing the system tasks and open-meteo api for

sourcing the weather data.

## Build Instructions

### Required components

- LOLIN32 Lite microcontroller (like this one [here](https://www.amazon.co.uk/AZDelivery-Lolin-ESP32-Parent/dp/B086V1P4BL?th=1))

- DHT22 temperature and humidity sensor (see [here](https://www.switchelectronics.co.uk/products/dht22-digital-temperature-and-humidity-sensor-module?variant=45334947561781&currency=GBP&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gclid=Cj0KCQjw9fqnBhDSARIsAHlcQYTC_RPZrCdsrJcMWFUb5oEbM2ZXBoalp3reoWo0Z95ebyMr20l00vMaAtPtEALw_wcB))

- infrared remote and receiver (example [here](https://www.ebay.co.uk/itm/154724697624?chn=ps&_trkparms=ispr%3D1&amdata=enc%3A1ZrJC8Xh7S1O-VXLV_YROyg39&_ul=GB&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&mkscid=101&itemid=154724697624&targetid=1647205088320&device=c&mktype=pla&googleloc=9045888&poi=&campaignid=17206177401&mkgroupid=136851690655&rlsatarget=pla-1647205088320&abcId=9300866&merchantid=113112059&gclid=Cj0KCQjw9fqnBhDSARIsAHlcQYSEzWP9kBIrCusp_EtkQ7L0MUGv69uRiiCi-RFfC8OKJTxTwdI5lzMaApxjEALw_wcB))

- small breadboard

- jumper wires

- some batter compatible with the microcontroller.

### Building the code

First you need to get the esp-idf framework set up on your machine. You can find

instuctions on how to do it [here](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/).

#### Installing esp-idf on Arch Linux

If you are fortunate enough to be using an Arch-based distribution, you can

download esp-idf using the following command:

```

sudo pacman -S esp-idf

```

After that you will be promted to install the python tool using:

```

/opt/esp-idf/install.sh

```

And then source all of them so that they are available in PATH environment

variable

```

source /opt/esp-idf/export.sh

```

I recommend aliasing the above command inside of your .bashrc / .zshrc as you will

need to run it in every new terminal window where you want to work with esp-idf

framework. An example of such alias can be seen below:

```

alias get_idf='source /opt/esp-idf/export.sh'

```

After that you need to set the wifi

password for the project using the command:

```

idf.py menuconfig

```

For convenience I recommend aliasing idf.py to idf in you shell config.

After you've done that, the project can be built, flashed onto the board and

started to be monitored using the following command:

```

./run

```

In case you want to modify the code and submit a pull request, make sure to

have clangd installed and run the formatting script before submitting the code

to avoid code style merge conflicts.

```

./reformat

```
