Simple sensorless weather station (OpenWeatherMap API)
Do you want to build up weather station but you have no sensors or spot where to place them? This video shows basics how to create simple system connected to free OpenWeatherMap API to obtain always fresh data about weather (for this project temperature, air humidity and air pressure). I go to use JSON parser for Arduino and HTTP GET request to obtain data from a remote server. For this project I'm using Lolin32 Lite (ESP32) but you can use any ESP32 or ESP8266. I try to keep the code below 100 lines.
In the second part (following video) we go to use TFT display to build up even more complex system together with some basic user settings (time zone, units etc.). Stay tuned :)
