- 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.
