The automation of pesticide spraying is one of the new techniques in agriculture field lately. This automation is very important since conventional pesticide spraying method that been used nowadays can be hazardous and at the same time brings handful toxic effect to fanner. Pesticide is a toxic solution or formulation which been used to control the pests and also unwanted plants. This project focuses .mainly to develop automated pesticide fluid delivery subsystem for the pesticide automation system. This automated spraying subsystem is a combination of mechanical and electronic concepts. The mechanical components used in this subsystem are such as DC pump, nozzle, hose and container. While the electronic components used relay as a main component to control the system.
