  Agricultural production using high technology is an inevitable trend in
Vietnam. Especially for material crops which typically need large growing
areas, wireless sensor networks has been clearly playing a significant role in
increasing productivity, monitoring pests and diseases, mitigating the impact
of climate change, and reducing the direct labor of cultivators. This paper
constructs an experimental model of agricultural crop field monitoring using a
combination of LoRa wireless sensor networks and unmanned aerial vehicles to
collect data on conditions of weather and soil, plant health, which helps
growers easily making right decisions on solutions for irrigation, pest
treatment, and fertilization with the currently planted crops. The system has
been developed and experimentized in the field to evaluate some basic features
and justified the stability and reliability of the obtained data.
