Web SCADA Employing Application Program Interface as Data Source

An Application Programming Interface or API is a set of routines, protocols, and tools for building software applications. A good API makes it easier to develop a program by providing all the building blocks. A programmer then puts the blocks together. Many companies provide free API services which can be utilized in Control Systems. SCADA is an example of a control system and it is a system that collects data from various sensors at a factory, plant or in other remote locations and then sends this data to a central computer which then manages and controls the data. In this paper, the authors designed a scheme for Weather Condition in Internet SCADA Environment utilizing data from an external Application Program Interface.
