Summary

Automated Planting System an innovative solution for automated plant watering, integrating various sensors and displays to ensure optimal plant care while providing real-time feedback to users. Our automated planting system will monitor soil moisture levels, water tank levels, and temperature, adjusting watering accordingly. Additionally, it will provide visual feedback through LED indicators and OLED displays for user convenience.

Print Settings

Printer brand:
Creality
Printer:
Ender 3
Rafts:
Doesn't Matter
Supports:
No
Resolution:
0.32
Infill:
20
Filament brand:
Fillamintuim Extrafill
Filament color:
Gray , Blue , Green
Filament material:
PLA
Notes:
For slicing, we constrain Creality Ender 3 as the main printer, with a 0.8 mm nozzle and PLA material.
For slicing settings, we increase shell and decrease infill for parts that need to be stronger, such as electronic enclosure and water tank. Conversely, we do the opposite for parts that need to be weaker, such as the leader and enclosure cover. Finally, we believe there is no need for supports for any of the 3D design components.

System Components

-Arduino UNO R3
-Breadboard
-Relay module
-Mini water pump
-Plastic Battery Storage Case Holder
-Jumper wires
-0.5m Vinyl Tubing
-Soil Moisture Detector Module
-LED 5mm Red ,LED 5mm Green, LED 5mm Yellow

-OLED DISPLAY MODULE

System Operation

-Soil Moisture Monitoring: The system continuously monitors soil moisture levels. When the moisture falls below a preset threshold, indicating the need for watering, the water pump is activated.

-Water Tank Level Check: The water tank level sensor regularly checks the water level. Based on the level detected, the LED indicators display green for above 50%, yellow for 20-50%, and red blinking light for below 20%.

-Water Pump Activation: If the water tank level is sufficient, the water pump is activated to supply water to the plants. If the water level falls below 20%, the alarm is triggered, and the water pump is shut down to prevent damage.

-Visual Feedback: LED indicators provide instant visual feedback on the water tank level, allowing users to take necessary actions such as refilling the tank. Also the OLED displays a message "Watering plant in progress" when the pump is active.

-Temperature Monitoring: The temperature sensor continuously monitors the ambient temperature and displays it on the OLED display, ensuring optimal growing conditions for the plants.

Electrical circuit design

NOTE :we've added relays to provide protection to the control circuit by isolating it from the high-voltage load circuit. Additionally, relays are robust and durable components designed to withstand frequent switching operations, ensuring the longevity and reliability of the system.
so , using relays with water pumps enhances safety, enables remote control, and ensures the efficient operation of the pump system.

3D Model Description

Notes:

The prototype‘s Dimensions are 200mmx150mmx150mm.
All these dimensions were taken into consideration in additive manufacturing design.
consideration of dimensions will enhance the quality, functionality, and efficiency of your
final product.

Components:
