Internet of things is a technology innovation which connects thousands of mil- lions of sensors and actuators. Platform is which provides both hardware and software service. There are so many platforms existed in the market. The objective of this study has been to answer the question which IoT platform fits bests for different scenarios by performing a quantitative comparison between SensibleThings and ThingWorx. The study has been conducted with the aid of my su- pervisor Stefan Forsström and professor TingTing Zhang. The study has shown that SensibleThings and ThingWorx both has its innovation features thus it fits to the different cases according to cases’ need. If the sensor need to update data quicker than 25 times/sec, it is better to choose ThingWorx. If the sensor doesn’t have good hardware it is better to use SensibleThings cause it is light- weight enough. For the case that more than one sensors’ data rush into one point simultaneously, ThingWorx has better performance. In this paper I use a health care system as an example. I think ThingWorx is more suitable for this case regard of its mature service on security and graphical visualization. Finally I presented my future work for platform evaluation.
