Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

IOT Sensor Project: ESP8266 with DHT11 Sensor sends Data to MQTT
We are almost there. for adding MQTT to our program, we will again use Adafruit libraries: Adafruit_MQTT and Adafruit_MQTT_Client. There is a great official example that shows the core aspects about how to use the library. After several tries, here is the working version.

Choosing an MQTT library
I got the built in LED blinking within a couple minutes. (Great Success! :D ) I haven't done as well with MQTT. :-/ I started following a tutorial at https://vimalb.github.io/IoT-ESP8266-Starter/Lesson_04/lesson.html and immediately ran into the header PubSubClient.h not found. I went into Tools -> Manage Libraries, entered "MQTT" in the search field and came up with over 30 libraries! Next I did a search for the missing header error message and that led me to https://github.com/Imroy/pubsubclient. I installed that and it gets me past the missing header, but when I try to create a PubSubClient I get error: no matching function for call to 'PubSubClient::PubSubClient()' which means there is no default constructor for this class. So I'm not sure if I have the wrong library or if it has been modified since the tutorial was written.
