ESP32 HTTP GET with OpenWeatherMaporg and ThingSpeakcom 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.
Temperature, Humidity and Weather Forecast with an ESP32 Circuit Diagram
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 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"). 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.
