DESIGN
The system designed here contains three main parts (1) The Smart mini Robot System
(2) plant system, and (3) communication system. The designed smart mini robot’s
architecture comprise of an ESP32 micro controller, which has a built-in Wi-Fi module, a
user must install an android application in an Android-based smartphone developed and
deployed in the Blynk server, which is an IoT cloud server. The plant system involves
the usage of a soil moisture sensor to monitor the moisture level of the soil or the plant
which is then processed using a micro controller to decide whether to active the
sprinkler and for how long. And lastly the communication system relies entirely on the
ESP32, which have been equipped by a build in WiFi. The robot is controlled remotely
trough an android application developed on the blink loT platform. The ESP32,
connected to a Wi-Fi network, maintains a continuous connection to this server and
receives the commands in real time. Upon receiving a command, it processes the
instruction and performs the appropriate action by controlling connected hardware
components such as motors, relays, or pumps. They are similar to our works in a
number of ways. Both involves micro controllers, communication systems, and plant
monitoring systems with different modules like the ESP32 micro controller, moisture
sensors, and other robotic components. They use the ESP32 board for processing and
wireless communication, a soil moisture sensor to measure soil humidity levels, and a
smartphone interface to enable users to monitor and control plant health remotely.
These system share a common goal: the automation and improvement of plant care
using intelligent technologies. These systems help achieve effective and timely plant
maintenance by allowing real-time data gathering, wireless communication, and user
access via mobile apps. The studies are also programmed to work with minimal human
intervention, focusing on automation and independence in system operation.
FUNCTIONS
The projects use watering systems that aim to automate irrigation through real-time soil
moisture monitoring. The role of the watering system is to sense soil moisture through
sensors and enable the ESP32 micro controller to control the amount of water and the
time to when the plant needs watering.This ensures water is provided only when
required and in optimal amounts. It also has remote control through a smartphone app
for manual or automated watering. It run independently, the plant has a sensor and
wireless module that requests when the soil is dry. The robot is given the signal, goes to
the respective plant, and gives the corresponding amount of water through an inbuilt
pump. No human effort is needed after installation, and the system provides targeted
watering for every plant separately. The watering system listed above has several of the
same elements as our research, such as an ESP32 microcontroller and a soil moisture
sensor, both of which are crucial for automation. The ESP32 board is tasked with
regulating the water dispensing system, while enabling accurate and timely irrigations
with real-time soil conditions. The moisture sensor continuously monitors the state of
hydration in the soil, enabling plants to be fed the necessary amount of water. A
smartphone is also utilized as a remote controller, enabling users to manually control
the system when required. Overall, our research is intended to advance agricultural
practices through minimized labor, water resource conservation, and precision farming
through smart technologies.
