Overview / Usage

It is a portable weather station once the code is uploaded to NodeMcu we don't have to modify it for connecting to any other network. Just have to press the button connected to pin D3 and an AP open for configuring the esp8266 for connecting to the network.

Methodology / Approach

The code is written in Arduino IDE and uses PubSub client to send the data of DHT11 sensor to the server. The code is written for esp8266 and also host a local server to send data on an HTML webpage the temperature and humidity. The code includes wifi manager library to set the trigger pin (D3) for the Access Point.
