In this project, we will learn how to create a weather station, which will display reading from a BME280 module and live weather data from OpenWeatherMap API in a webserver.

Data is a crucial resource for any kind of analysis and forecasting. It is always needed to create any information or stats.

Many IoT cloud platforms have emerged in the last few years to cater to the increasing network of IoT devices.

A weather station is a device that can monitor various parameters like humidity, temperature, pressure, rainfall, etc. of the surrounding environment. We previously built a few weather stations using a different microcontroller like:

In this tutorial, we will make an ESP32 based Weather station in which we will build an ESP32 Webserver to display temperature, humidity, pressure, luminosity, and altitude values on a web browser.

There are various wireless communication technologies used in building IoT applications and RF (Radio Frequency) is one of them. nRF24L01 is a single-chip radio transceiver module that operates on 2.4 - 2.5 GHz (ISM band).

Climate change has led to unpredictable weather conditions. There are many weather stations around the world that are used by researchers and government agencies to observe, record, and analyze weather patterns to study climate changes and provide weather forecasts.

According to a report there will be over 20.4 Billion connected things worldwide by 2020. IoT platforms are the main facilitators in the growth of connected devices.

Node-RED is a visual tool for non-programmers to work with the Internet of Things, it can be used to build application fasters and reduce the “go to market” time for IoT products.

Global warming has lead to unpredictable climates; researchers around the world are using weather stations to observe record and analyze weather patterns to study climate changes and provide weather forecasts.
