Section for weather station. Throughout this section, our main goal will be to implement a weather station. But as you know, in no trade, you can end up with the same solution in different ways. And that is what we'll be looking at. Video 4.1 using open weather map node. In this video, we will be building a weather station using an already available node called Open weather map.

Before we start, what is a weather station? It is a facility to study weather and climate. It gives you various weather data, like temperature, humidity, atmospheric pressure, wind speed, wind direction, precipitation amounts, and information about clouds. So what do we need to be The weather station, we need to arrange for our own weather data or get it from somewhere. For now, we're going to get the weather data using open weather map note. You can also use wonder ground or dark sky or any other weather nodes, which you will find in the Manage palette.

First, let's install the open weather map node. There are two nodes. One is an input node, which means it gets data from open weather map API. And the other one is a query node, which accepts location data and returns weather for that location. Let's see what's the input node outputs. Like I've told you, all API's have some authentication technique because in today's world, data is more important than anything Get an account in the open weather map website and get the API keys.

I already have an account. And I'll be using the API key from that the API key created for you has not been activated yet. It will take a couple of hours for it to get activated, after which you can use it. By default, you will get access to the free account. If you want specialized data, then you have to subscribe for more. You can check your plan to see the API calls per minute allowed for your plan.

Use the API key in the node and configure it as per your wish. Connect a debug node to see the output. Wait for some time till your API key has been activated. then deploy and see. As you can see, you're getting a lot of weather data along with your location info. You can even get humidity pressure, wind speed, sunrise and sunset data.

That is quite a lot of data. Next, we can try the query note. Here, we have to pass the location data inside the message object. You can either send city and country information or latitude and longitude information. I'm using a change node to set them. deploy an oopsie forgot to set the API key.

Okay, now check Now I want you to pause the video and try storing the whole message object as data in the Cloudant database, whether underscore data done. Let's check the database. Good job if you have got the way the data stored in there. If you're bored, then try adding a chart node, the query node have open weather map and a repeated inject node and plots the climate data. Or you can post tweets with the description parameter in the data we got. In this video, we saw how to build a weather station using The open weather map node.

It is going to get interesting as we proceed, and you will definitely be caught under the magic spell of node red. In the next video, we'll build the same weather station using a web API.
