BMP280 Based IoT Weather Station using ESP8266 & OLED Display

Today in this tutorial, we will learn to interface the BMP280 sensor with the NodeMCU ESP8266 development board, then monitor its parameters like temperature, barometric pressure, and altitude, on the 0.96 inch OLED display and also on the Blynk IoT Platform. This IoT Project provides your NodeMCU ESP8266 board the ability to sense the environment with a BMP280 Barometric Pressure sensor. Overall, we are building ESP8266 & BMP280 based IoT Weather Station.
