My assumption is that you want to read your sensors at periodic time intervals, whether or not you are looking at them from the web interface. You can do this with the web2py scheduler but I think it is overkill. I would just create a process that loops and records he sensors in your database (or perhaps a CSV file). Then your web app just reads the data displays it to the user and makes plots.
