SoilGuard aspires to make irrigation more
intelligent, trustworthy, and waste-free by moving away
from conventional guesswork and preset watering
schedules to real-time, data-driven decision-making. The
system allows farmers to understand actual field
conditions rather than regular schedules or observation
by monitoring the exact amount of moisture in the soil
using tiny IoT sensors. These readings are continuously
collected by the ESP8266 microcontroller and uploaded
to the Blynk cloud platform, enabling users to easily and
conveniently monitor their soil status from any location.
Over time, accumulation of more data enables an LSTM
to learn how the soil changes throughout the day-that is,
how rapidly it dries out, how it responds to changing
weather conditions, and how long it remains wet after
irrigation. The model uses these patterns that it has
learned to make educated guesses as to when the moisture
level will fall below a healthy threshold. The system uses
a relay that automatically switches on the water pump
before the soil dries up. This makes sure plants get water
whenever they need it without needing constant
supervision or someone else's attention. As compared
with simple systems working on the basis of thresholds,
this method of prediction works much faster and more
effectively. That helps to minimize wasting too much
water; thus, the soil moisture levels can stay healthier.
SoilGuard has been tested for its consistency and quick
response, by ensuring a good amount of water is saved;
hence, it is practical, affordable, and reliable for farmers
who would like to experience a more modernized means
of irrigation management that is eco-friendly.
