This book presented a complete implementation of an embedded controlled smart security system, which is capable of detecting the presence of object without any human intervention. For detecting the object, we have designed and implemented Time-of-Flight (ToF) measurement based novel Top Edge Detection (TED) algorithm. By executing the TED algorithm, a moveable sensor plate will arrive at a position followed by the top edge of the object. From this position, the image capturing sensor captures an instance image of the object. After capturing the image, it is compressed before being sent into...

At present, autonomous wireless sensor network (WSN) components are extensively powered up using batteries. Due to limitations in batteries, it incurs huge maintenance cost and for remote and inaccessible areas battery replacement is simply impossible. To overcome this issue, an integrated Energy Harvester (EH) is proposed and developed here. Solar based EH has been identified as the most viable source of energy to be harvested for WSN components. Moreover, a novel chemical based EH is reported as the potential secondary source for harvesting energy because of its uninterrupted availability....
