ESP8266 weather station using Arduino IDE

Today we are making really cool weather station using ESP8266 (NodeMCU) and DHT11, rain sensor. In this project, we’ll learn how to make a DIY fully featured weather station using an ESP8266 and sensors. There are two types of weather station, one which is having own sensors and second type of weather station is where we pull data from the weather station servers. In this tutorial we are looking at both types of weather stations.

ESP8266 or ESP32 I2C LCD display Interface

In IoT, LCD is rarely required, but some times its useful to monitor errors and connection related issues. In this tutorial we are interfacing I2C LCD with ESP8266 or ESP32. Both code examples are given.

We have very few IOs on ESP8266 and ESP32. I2C based display interface uses only two IO lines.
