I want to send data from an arduino uno to nodered using mqtt. In my project i am connecting gas sensors and temperature and humidity sensors to uno board. After receiving the data i want to send it to nodered.
I dont want to use a local broker that is installed in my pc rather i want to send it through awsiot broker.
To access the awsiot broker should i be connected to the internet. If yes i want to connect the arduino to the internet using an esp8266-01 since i have one with me. I don't wanna buy any other shield. If this is possible please help me out.
This is my first post on any forum so kindly excuse me if i have broken any rules and do feel free to point out my mistakes so that i don't repeat them.
