OpenWeatherMap (OWM) provides a robust, standardized icon set for visualizing weather conditions, integrated directly into their weather API data. These icons are designed to represent various weather phenomena—such as rain, snow, and thunder—and automatically handle day/night distinctions. They are frequently used in IoT weather stations (ESP32/ESP8266) and web applications to provide at-a-glance meteorological information. 2. Icon Structure and Access
Using JavaScript, the icon code is retrieved from the JSON response and updated in the HTML tag.
