Step 2 : ArduinoJson Library:

You also have to install the ArduinoJson library. Follow the next step to install the library.

1. Go To Sketch > Include Library > Manage Libraries.

2. Search for "ArduinoJson".

3. Select the latest version available.

4. Install the library.

Step 3 : To establish communication with the Telegram bot, we’ll be using the Universal Telegram Bot Library created by Brian Lough that provides an easy interface for Telegram Bot API.

Follow the next steps to install the latest release of the library.

• Ultilize the DHT11 sensor to monitor temperature and humidity readings through Telegram Bot.

• Required components : ESP8266, DHT11, three female-to-female jumper

Step 1 : Connect the jumper as the shown picture, pin D4 :

Step 2 : Copy and paste the code to Arduino IDE

- "wifi name" to your own WiFi

- "wifi password" as your WiFi password

- "botfather token" to the token you get
