Reflection

I learned how to add a sensor into the device and using sending messages to the phone. I found it interesting that the device can be done in a not difficult way that I have never seen before. However, it is still a very simple prototype, it does not have good user experience and has limited functions. I think this product can be improved by adding a push button that shows the person has finished grooming, or it can be improved by notifying people more naturally, maybe on a watch. Further, I need to learn about more advanced loop so that it can be used in more complex situations, for example, someone enters, leaves and then enters again within a very short period of time, how to present the information is still a question for me.
