The internet of things (IoT) refers to an ever-growing network of physical objects which are connected to the internet. This includes household devices and many business and industrial applications. The IoT has given way to a vast array of new products and services. Take for example fill-level sensors developed by smartbinTM. These products can be placed inside industrial bins and send data on the fill level and bin location back to the waste collection firm via an internet connection. The sensors also allow the waste collection firm to optimize the waste collection routes.
Question:

Can you think of any barriers to entry for a business entering the market for IoT sensors or similar?
