i wrote my own module

i also use the blynk mobile app to display the data in near realtime…

There are several ways to do so. First important thing to know is how you get and store your data. Do you want to collect the data and store it in a csv/xml/json/… file? Do you have an interface to retrieve data from, maybe a little webserver for the sensors?
