The project was to build a system where plants can get water automatically by sensing their soil moisture level. Here we have used Arduino UNO, Soil Moisture Sensor, etc to build the system.

3. OVERVIEW
So what is this project about? What does it
do?
Basically this is a soil moisture monitoring
system, which detects if the moisture content in
the soil is above or below a certain satisfactory
threshold value. If it goes below a certain critical
point, it is time to water the plant and an
arrangement of a DC motor is used to control the
watering mechanism here in this project.

11. WORKING PRINCIPLE
• The Soil moisture sensor continuously
monitors the volumetric moisture content in
the soil and sends that information to the
Arduino.
• If the soil moisture content goes below a
certain point, which is decided by the
threshold value given in the Arduino code,
and the DC motor to start watering
mechanism.

12. WORKING PRINCIPLE
• As soon as the Arduino decides that the
soil needs watering , it tells the relay to
switch on the pump.
• The pump motor, i.e., the DC Motor is
running to maintain a steady flow of
water to the pot.

18. ADVANTAGES
 It's a time saving procedure.
 Eliminates manual task.
 It's a very particular process, that
means water is effectively targeted
only where it is needed.

19. DISADVANTAGES
 The system can be very expensive.
 It requires electricity.

21. CONCLUSION
 The primary applications for this project are for farmer sand
gardeners who do not have enough time to water their
crops/plants.
 The project can be extended to green houses where manual
supervision is far and few in between.
 The principle can be extended to create fully automated
gardens and farmlands.
 In agricultural lands with severe shortage of rainfall, this model
can be successfully applied to achieve great results with most
types of soil.
