DESIGN AND FABRICATION OF SOLAR POWERED PESTICIDE SPRAYER

Protecting crops against weeds, insect pest, and germ is becoming a biggest challenge for the farmers. To overcome this issue. chemicals (pesticides) are applied to crops For this purpose a pesticide sprayer are used. Sprayers are mechanical devices that are specifically designed to spray Chemicals quickly and easily. A sprayer of this type is a great way to use solar energy. Solar based pesticides sprayer pump is one of the improved version of petrol engine pesticide sprayer pump and hand pump sprayer. It is vastly used in the agriculture field & also used for many purposes. This is having more advantages over petrol engine sprayer pump. It uses the solar power to run the motor. So, it is a pollution free pump compared to petrol engine sprayer pump. The solar panels make up most (up to 80%) of the systems cost. The solar sprayer has many advantages. Besides reducing the cost of spraying, there is a saving on fuel/petrol. Also Reduces man effects in case of hand sprayer. The solar sprayer maintenance is simple. The operation of solar powered pumps is more economical mainly due to the lower operation and maintenance costs and has less environmental impact. Solar pumps are useful where grid electricity is unavailable and alternative sources. The farmer can do the spraying operation by himself without engaging labour, thus increasing spraying efficiency. In this context, we have proposed an innovative sprayer model for optimized spray applications with minimum losses and cost. The proposed working model of automated pesticide sprayer was designed, fabricated and analysed for performance tests. This sprayer operates on electrical power supplied by solar panel with battery of designed capacity. An added advantage of this automated pesticide sprayer is that it does not have any impact as far as farmers health is concerned and also it is free from greenhouse gas emissions. It has also been proven itself to be an efficient, reliable and economical one to spray pesticides for agriculture applications.
