2. Introduction
The delicate balance between climatic conditions and the specific moisture needs of plants is crucial for
their optimal growth and development. Precipitation, being an essential source of water, plays a
fundamental role in vital processes such as photosynthesis, nutrient supply and thermal regulation.
Lack of precipitation can lead to water stress, plant wilting and damage, while a constant supply of water
and nutrients will boost growth, promoting a healthier appearance and preventing water stress that can
reduce growth and increase susceptibility to disease.

3. Summary:
The goal of the project is to create an advanced rainfall and humidity sensor that will enable accurate
and efficient measurement of environmental factors that affect plant health. The project seeks to better
understand the needs of your plants by combining sensor technology with knowledge of electrical
circuits. Measuring and analyzing soil moisture and rainfall contributes to healthier and more sustainable
plant growth.
In addition, this project aims to have an emphasis in the field of electronics and circuitry. Also, to the
Development of skills in sensor programming and circuit creation. This will encourage learning and
exploration in technology.

6. Problem statement
Plants are an essential part of terrestrial ecosystems and play an important role in air purification,
the water cycle, and the provision of food and shelter for wildlife. However, environmental factors,
including poor rainfall and humidity conditions, threaten their health and vitality. There is an
increase in the frequency and intensity of extreme weather events, such as prolonged droughts and
torrential rains, which may cause imbalances in water supply to plants as climate change
intensifies.

14. Preliminary results
This project has been devoted to the study of plant vitality in relation to important environmental factors such as
soil moisture and precipitation. Important conclusions have been reached that give us a deeper understanding of
the dynamics between these important factors and plant health. Accurate and detailed data collection was
achieved through setups equipped with specialized sensors, allowing for rigorous analysis.
Statistical analysis showed a significant correlation between soil moisture and rainfall and several
vitality indicators, such as growth rate, chlorophyll content and disease resistance. These
interactions highlight the complexity of environmental factors in the plant growth environment.

Sensor assemblies have proven crucial for real-time data collection, allowing for a more detailed and dynamic
understanding of environmental conditions. This demonstrates how crucial continuous monitoring is to adapt
to seasonal changes and climatic shifts.

16. Conclusions
The findings of this project provide new insights for sustainable agriculture and crop
management. The ability to anticipate and respond to changes in moisture and rainfall
can significantly increase agricultural productivity and reduce the risk of losses.
In summary, this project has increased scientific understanding of the interaction
between moisture, rainfall and plant vitality. Furthermore, it has demonstrated that
sensor technology is essential for a more accurate and applied understanding of
these phenomena. These findings have direct practical implications for improving
agricultural practices and resource management, as well as providing a solid
foundation for future research.
