Adaptive switching techniques of power scavenging in WSN for industries

For explicit use of Wireless Sensor Network (WSN), its energy demand should be fulfilled continuously, conventionally which is provided by batteries. A power scavenging technique, searches alternative energy option so as to provide long operational life. A very effective method to increase efficiency of solar panel, a power feedback MPP technique for tracking maximum power point of solar panel at which it gives maximum output is discussed in this paper. A power transferring circuit for optimally conveying solar energy into rechargeable batteries even in not optimal weather conditions is also suggested. The suggested implementation is particularly effective in critical weather conditions where traditional solutions do not work. Use of Ultracapacitor in place of alkaline batteries provides high power density.
