Solar Based Electric Fence for Smart Farming
Abstract: Animals create problems for farmers in their fields. By using electric fences farmers can protect their fields, farmhouses, farmlands from animals. These control the animals by giving them a short, sharp but safe shock that teaches them to stay away from the fence. Thus electric fences are economical and practical solutions to maximize field production through controlled grazing. Electric fencing is safe, as its output is discrete. There is certain …
