IOT BASED LOW-COST PRECISION INDOOR FARMINGMadhu Lekha Guntaka (11211111) 30 July 2021 (has links)
<p>There is a growing demand for
indoor farm management systems that can track plant growth, allow automatic
control and aid in real-time decision making. Internet of Thing (IoT)-based
solutions are being applied to meet these needs and numerous researchers have
created prototypes for meeting specific needs using sensors, algorithms, and
automations. However, limited studies are available that report on comprehensive
large-scale experiments to test various aspects related to availability, scalability
and reliability of sensors and actuators used in low-cost indoor farms. The
purpose of this study was to develop a low-cost, IoT devices driven indoor farm
as a testbed for growing microgreens and other experimental crops. The testbed
was designed using off-the-shelf sensors and actuators for conducting research experiments,
addressing identified challenges, and utilizing remotely acquired data for developing
an intelligent farm management system. The sensors were used for collecting and
monitoring electrical conductivity (EC), pH and dissolved oxygen (DO) levels of
the nutrient solution, light intensity, environmental variables, and imagery
data. The control of light emitting diodes (LEDs), irrigation pumps, and camera
modules was carried out using commercially available components. All the
sensors and actuators were remotely monitored, controlled, and coordinated
using a cloud-based dashboard, Raspberry Pis, and Arduino microcontrollers. To
implement a reliable, real-time control of actuators, edge computing was used
as it helped in minimizing latency and identifying anomalies.</p>
<p>Decision
making about overall system performance and harvesting schedule was accomplished
by providing alerts on anomalies in the sensors and actuators and through installation
of cameras to predict yield of microgreens, respectively. A split-plot
statistical design was used to evaluate the effect of lighting, nutrition
solution concentration, seed density, and day of harvest on the growth of
microgreens. This study complements and expands past efforts by other
researchers on building a low cost IoT-based indoor farm. While the experience
with the testbed demonstrates its real-world potential of conducting experimental
research, some major lessons were learnt along the way that could be used for
future enhancements.</p>

Fast and Accurate Image Feature Detection for On-The-Go Field Monitoring Through Precision Agriculture. Computer Predictive Modelling for Farm Image Detection and Classification with Convolution Neural Network (CNN)Abdullahi, Halimatu S. January 2020 (has links)
This study aimed to develop a novel end-to-end plant diagnosis model for the
analysis of plant health conditions in near real-time to optimize the rate of
production on farmlands for an intensive, yet environmentally safe farming
production to preserve the natural environment.
First, field research was conducted to determine the extent of the problems
faced by farmers in agricultural production. This allowed us to refine the
research statement and the level of technology involved in the production
processes. The advantages of unmanned aerial systems were exploited in the
continuous monitoring of farm plantations to develop automated and accurate
measures of farm conditions.
To this end, this thesis applies the Precision Agricultural technology as a data based management system that takes into account spatial variations by using
the Global Positioning System, Geographical Information System, remote
sensing, yield monitors, mapping, and guidance system for variable rate
applications.
An unmanned aerial vehicle embedded with an optic and radiometric sensor
was used to obtain high spectral resolution images of plantation status during
normal production/growth cycle. Then, an ensemble of classifiers with Convolution Neural Networks (CNN) was used as off the shelf feature extractor
to train images to develop an end-to-end feature detection and multiclass
classification system for plant overall health’s conditions. Whereby previous
works have concentrated on using CNN as off the shelf feature extractor and
model training to detect only plant diseases from plants.
To date, no research has yet been carried out to develop an end-to-end model
for the overall plant diagnosis system. Previous studies focused on the
detection of diseases at any given time, making it difficult to implement
comprehensive real-time PA systems.
Applying the pretrained model to the new images showed that the model can
accurately predict any plant condition with an average of 97% accuracy.

Landtechnik der Zukunft - Großtraktoren + Giganten oder Feldschwärme04 April 2018 (has links) (PDF)
Landtechnik der Zukunft
Die fortschreitende Digitalisierung betrifft sämtliche Lebensbereiche. Als Chance und Herausforderung zugleich geht es momentan darum auch in der Landwirtschaft Nutzen und Ziele zu definieren, Voraussetzungen zur Einführung zu schaffen und Anwender und Verbraucher auf dem Weg mitzunehmen. Die Veranstaltung Landtechnik der Zukunft, beleuchtete diese Themen am 23. Januar 2018 in der Vertretung des Freistaates Sachsen beim Bund in Berlin.
Zukunftstechnologien und deren Praxisanforderungen wurden mit renommierten Referenten interaktiv diskutiert und auch dokumentiert. Szenarien einer digitalisierten und nachhaltigen Landwirtschaft gekoppelt mit aktuellen Ernährungstrends prägten die Veranstaltung, deren Teilnehmer querbeet aus Industrie, Politik und Hochschule kamen. Schwarmtechnologien wie auch die echtzeitfähige Funkvernetzung für Arbeitsmaschinen und -prozesse erzeugten viele Nachfragen, wobei Technikentwicklung im ökologischen Landbau und Technikentwicklung für Nachhaltigkeit aus der Sicht der Hersteller im Kern des Interesses waren.
