I need some project ideas for Arduino UNO with MQTT project.
I have successfully tried connecting Temperature sensor with a MQTT server,and received the published temperature messages in an Android program in mobile.
Now,I want to expand this idea.
1)Either I can go with same temperature sensor and other supported sensors with Arduino UNO to act as subscriber MQTT client and perform some usecase(eg :Running a fan based upon temperature.But not sure how to connect fan setup with Arduino and run it based upon subscribed data.Need help on this one too..).
2)Or...I can entirely try with new set of use case with supported sensors with Arduino UNO.
Please provide me some ideas and also the supported sensors with Arduino UNO...
