The emergence of many internet industries ushers in IOT era, and about to bring us to the point of universal connectivity. In the field of education, the IOT technology has a broad applicable prospect for a more interactive and intelligent way by improving the quality of teaching and management. The proposed class affair management system is mean to enrich the interaction between lecturers and students which in an efficient and smart way. Based on the existing model, a layered architecture is proposed to build the beacon based campus management system. Backend device and protocols compose the physical layer to collect the raw data from physical objects. Data link layer and control layer are responsible for forming required package and sending to corresponding layer. Beacon technology used for proposed design applies Bluetooth low energy 4.0 standard which allowing devices exchange data through Bluetooth at an extremely low power consumption-using a single coin cell battery can last for several years. Saved up to 97 percentage energy compared with similar system. The entire proposed platform allows participants to bring personally owned devices to access campus management system. Through location information, teaching activities and personalized information notification can be automatically accomplished, which will inspire the innovation and development of classroom teaching mode. Beacon technology has a great potential that can be completely transplanted into other scenario such as the hypermarket and library.

The world demand for alternative energy source has increased with the consumption of energy increasing tenfold in the past five decades. Solar power generation is one such alternative, and Concentrated Photovoltaic Technology (CPV) is one of the two main technologies used for producing electricity from Concentrated Solar Power (CSP). Meteorological parameters such as solar irradiance and cell temperature when the sunlight is concentrated on the CPV module influence the efficiency of the CPV power generation systems. Additionally, the output power of a CPV plant must be measured and monitored to improve the condition of plant, again in terms of efficiency and reliability. Firstly, in this paper, the significance of the meteorological parameters and the CPV system parameters are discussed. This is followed by a description of proposed multichannel data acquisition and logger for CPV technology. Experimental results have proven a good level of accuracy of the proposed system in terms of the acquired meteorological parameters and CPV system parameters.
