The problem Drip irrigation using iot solves

Water scarcity:- The amount of water that can be physically accessed varies as supply and
demand changes.
Agriculture accounts for 70% of all water use,in agriculture water wastage is maximum

Challenges we ran into

In today's world, technology is continually evolving in order to reduce human labour
through the use of IOT, artificial intelligence, and machine learning. It is extremely difficult
to grow any agricultural food in areas with sporadic rainfall patterns and high mean
temperatures, putting additional pressure on farmers to irrigate at regular intervals without
any basic understanding of the rainfall pattern and soil humidity. The crop-plant is either
under-watered or over-watered as a result of the ignorance and irregular irrigation. This study
attempts to create a basic and low-cost automatic watering system utilising a soil moisture
sensor, a DHT11 sensor, and a NodeMCU. To accurately manage the water levels required
by each unique plant, a fuzzy logic model based on soil moisture, temperature, humidity, and
precipitation forecast is being developed. Finally, this model is fuelled by solar energy, which
not only helps in achieving true independence from conventional forms but also helps to
lessen the carbon footprint problem.
