IoT Weather Monitoring System using NodeMCU ESP8266 & OLED Display & DHT11 Sensor | Full Tutorial
In this video, I will show you how to make a smart Weather Monitoring System using the NodeMCU ESP8266 WiFi module. We will measure real-time Temperature and Humidity using the DHT11 sensor and display the data on a 0.96" OLED Display.
This is a perfect project for beginners interested in IoT, Electronics, and Arduino coding!
