Abstract
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.
