Agriculture has a predominant role in our day to day life. Spraying of pesticides is an important task in agriculture for protecting the crops from pests. The conventional methods were person carrying a sprayer and manually actuating a lever to generate and pump the pesticide through a tube or a mobile vehicle carrying an inbuilt compressor and sprayer unit. Another major drawback in human operated systems is that the operator is exposed to the harmful chemicals while spraying which is extremely detrimental to operator’s health. A solar powered semi-automatic pesticide sprayer model consists of a solar panel, a battery, two DC motors, pump, container, Arduino device which is operated by a wifi ( range is 30 to 50meters) which runs on power source as a DC battery(12V, 1.7Ah). The capacity of the container in the sprayer was designed with 20 liters capacity for an uninterrupted operation of 10 minutes. Analysis of solar radiation data from Bangalore showed that the sprayer can be best operated during 9 AM to 5 PM. The vehicle is powered using an onboard solar powered battery which runs down the running cost. Besides reducing the cost of spraying, there is a saving on fuel as well. The farmers can do the spraying operation without human interference thus protecting them from noxious chemicals.
