Weather Display with ESP32 and OpenWeatherMap API Circuit Diagram This project serves as an excellent introduction to working with APIs, Wi-Fi connectivity, and data display on an LCD module using the ESP32 board. With the IoT Open Weather Display, you can conveniently access real-time weather updates at a glance, making it an ideal solution for home or office environments. Required Components
Introduction. In this project, we'll create a simple, real-time weather station using ESP32 and DHT11 sensor to monitor temperature and humidity. The ESP32 will operate in Access Point (AP) mode, allowing it to host a web interface that displays temperature and humidity readings in real-time, which can be accessed by any nearby device without an internet connection. Learn how to build an advanced ESP32 Weather Station using IoT technology. This step-by-step tutorial covers real-time weather monitoring, data logging, and ESP32 supports various protocols, but MQTT (Message Queuing Telemetry Transport) is particularly effective due to its lightweight nature well-suited for low-bandwidth networks. Implementing MQTT will allow you to publish real-time updates on your weather conditions effortlessly.

For our simple internet weather station, I am going to extract four pieces of information. The short description of the weather under weather -> main ("Clouds"), the current temperature under main -> temp (10.29), the current relative humidity under main -> humidity (82), and the name of the location under name ("Melbourne"). To receive data on Blynk from ESP32, you will have to create datastreams. First go to 'Datastreams' ; Under 'New Datastream' select 'Virtual Pin' ; The first datastream is named as 'Temperature' ; Select 'V0' under Pin ; Data Type will be 'Double' because we are receiving accurate values with decimal places ; Unit will be Celcius (ยฐC) 'Minimum Value' can be kept as 0 and 'Maximum Value' as 100
