This project was developed to need for a system that generates non conventional energy. Energy crisis is one of the major issues worldwide. This paper proposes maximum utilization of human locomotion energy for power generation using Piezo electric sensors. The basic principle was, any vibration or pressure that generate between surface and footsteps while walking, is converted into electric energy using Piezo electric transducers. A series connection of Piezo electric transducers are mounted on the tile and this tile is placed in the crowded area for the generation of electric energy. This paper explores the power generated by footsteps and used for mobile charging.

In this paper a Li-Fi and Wi-Fi-based weather monitoring system is built using drone. The atmospheric conditions are monitored using the drone and the gathered information is communicated to the ground station using Li-Fi technology. The process of transfer of information involves gathering data using sensors and transfer of data using Li-Fi technology. Data is processed and sent to the receiving station by using Light Fidelity technology. The received data is uploaded to a cloud data base using Wi-Fi technology. Real time data is displayed in an android device using IOT technology. Increased used of wireless communication which used Radio Frequency leads to RF congestion. Light Fidelity system is a best alternative by using a visible light instead of Radio frequency as used by all wireless communication system.

Before following any teaching technique, it is very important to Learn the Learner and then to implement the teaching technique based on the learner's capability. Hence, I propose Learner-centered Teaching methodology [LCTM] or Student-Centric Teaching Technique [SCTT].
