Make trend of an digital input

Hi. I have a digital signal how I want to make an trend how often the input is on, and also how long the input is on. I want this trend to be saved for later and also viewed over the internet. I have wi-fi access.

Please help me with hardware requirement and scetch for this project.

The signal conditioning hardware requirements depend on the nature of the signal (voltage, velocity...). Further requirements depend on the timing and amount of information, and on the library coming with your wi-fi module.

Split you project into the data acquisition, for which you have to write your own code, and the data transmission, for which you can use the library and related example code. If you have absolutely no idea where to start, hire somebody to make it all for you.
