Resumo
The competition between cultures of agricultural interest and invasive plants is a
problem that lasts several years, therefore, the industries of agricultural pesticides are
the most benefit from this gap in agriculture. But the effects of these pesticides are
not yet fully known. Based on this, the goals of this work are to build and evaluate an
unmanned ground vehicle, spraying system with fractioned dose; study of
photoelectric optical sensor use HC-SR501 PIR, real-time detection of invasive plants
in two different surfaces (surface red Latosol, light surface), with five different
infestation indices for both; develop a computational program in C language for a lowcost electronics that scan the information captured by the sensor and reverse flow
control. Construction and study were conducted at the Federal University of Mato
Grosso, câmpus of Rondonópolis, the evaluations were carried out in the experimental
area of Agricultural and environmental engineering course, on various conditions
(temperature, relative humidity and dust), the split spray system work properly the
activity to which it was designed; the VTA proved to be a suitable structure to the
study of sensors; the HC-SR501 sensor PIR detected the infrared reflectance of
different leaf areas which was submitted, but without reliable results, being the clear
surface presented more sense failure.
