T&D web storage services what else can be measured?

I've had a look at T&D web storage services which can measure temperature or humidity in removal trucks and send them wirelessly back to base where they can be accessed on the internet by a web browser. I would like to be able to transmit other data not just temperature/humidity such as, weight on a pressure mat in a loading bay entrance, or number of keystrokes typed on the keyboard of each PC in the office during working hours. How can this be done, does T&D supply the best hardware for this purpose, or what setup would you recommend?
