ESP32 Arduino : Fetching Current Weather Data (No JSON Parsing)

Advertisement

ESP32 Arduino means, an ESP32 dev board (which costs $8) and Arduino IDE configured for ESP32 in the way we described in an earlier guides. Our examples with IBM Watson IoT not fully easy guides for the newbie. This guide on Internet of Things (IoT) is relatively easier than them.

ESP32 Arduino Fetching Current Weather Data No JSON Parsing

To follow this guide, you need to sign-up for free account on OpenWeatherMap :

Vim
1
https://openweathermap.org/api

They will send an email with API key. It takes around an hour after new account creation to get the API working. The code like our other codes (like to read a response) :

#include <WiFi.h>
#include <HTTPClient.h>
const char* ssid = "yourNetworkName";
const char* password =  "yourNetworkPass";
const String endpoint = "api.openweathermap.org/data/2.5/weather?q=Kolkata,IN&APPID=";
const String key = "yourAPIkey";
void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi..");
  }
  Serial.println("Connected to the WiFi network");
}
void loop() {
  if ((WiFi.status() == WL_CONNECTED)) { //Check the current connection status
    HTTPClient http;
    http.begin(endpoint + key); //construct the URL
    int httpCode = http.GET();  //send request
    if (httpCode > 0) {  
        String payload = http.getString();
        Serial.println(httpCode);
        Serial.println(payload);
      }
    else {
      Serial.println("Error on HTTP request");
    }
 
    http.end();
  }
  delay(30000);
}

Open the serial monitor of Arduino IDE and you will get output like :

Vim
1
2
200
{"coord":{"lon":88.35,"lat":22.57},"weather":[{"id":721,"main":"Haze","description":"haze","icon":"50n"}],"base":"stations","main":{"temp":299.15,"pressure":1004,"humidity":88,"temp_min":299.15,"temp_max":299.15},"visibility":4000,"wind":{"speed":3.6,"deg":170},"clouds":{"all":40},"dt":1559497631,"sys":{"type":1,"id":9114,"message":0.0047,"country":"IN","sunrise":1559431309,"sunset":1559479650},"timezone":19800,"id":1275004,"name":"Kolkata","cod":200}

Obviously, you can change the city reading their documentation :

Vim
1
https://openweathermap.org/current

I have shown Kolkata, India in the above example :

Vim
1
const String endpoint = "api.openweathermap.org/data/2.5/weather?q=Kolkata,IN&APPID=";

It is JSON response. To make it human readable data we need to parse it using some other Arduino Library such as ArduinoJSON and some extra code :

Vim
1
https://arduinojson.org/v6/example/

Parsing JSON response requires work with basic things than starting with an HTTP response. The above ArduinoJSON library has an assistant :

Vim
1
https://arduinojson.org/v6/assistant/

We wanted to show a simple example of sending API request to fetch data. You can also read our similar guide on how to fetch time using ESP32 Arduino. We can deserialize using one line of code :

Vim
1
deserializeJson(doc, wifiClient);

You can try yourself to code to print the values.
