The advent and flourish of I.o.T. brings in new business opportunities. In the past, failures could only be deduced from the quality of end products. Once a product defect is reported, it may take an enormous amount of time and effort to track the problem. It is also difficult to clarify issues afterwards. To date, Sunshine Energy assists its customers in adopting I.o.T. to prevent the similar matter from happening. The sensors can record every detail of the production process on the continuous basis. Once the temperatures, humidity and voltages are being recorded, one can not only track the production process in each lot but identify an optimal production curve and formulate a range of upper and lower limits. When an abnormal condition occurs, one can take rapid actions to avoid product loss and ensure the quality.
