Wet! a Simple Automated Garden Watering System With Arduino UNO


Water is essential for maintaining a healthy garden, and efficient watering is crucial for nurturing plants while conserving resources. This guide outlines how to create an automated garden watering system designed to optimize water usage for your plants. By incorporating sensors and pumps, this system ensures that your garden receives the perfect amount of water at the right intervals.
With this automated setup, soil moisture levels are continuously monitored, allowing you to water only when necessary. This not only fosters healthier plant growth but also significantly reduces water waste. Additionally, the system can be programmed to adjust watering schedules based on weather conditions, ensuring that your garden thrives regardless of external factors. Enjoy a flourishing garden while saving time and resources with this innovative watering solution!
Here's a breakdown of the system's core components and their functions:
1. Soil Moisture Sensor:
- Location: Placed in the center of the open farmland.
- Function: Continuously measures the water content in the soil. This data is the primary input for determining irrigation needs.
2. Watering Tank and Pump:
- Location: Contains water for direct irrigation of the farmland.
- Function: A water pump connected to this tank is activated based on predefined soil moisture thresholds. When the soil moisture level drops below a certain threshold, the pump activates to irrigate the crops.
3. Reservoir Tank and Pump:
- Location: A larger tank connected to the watering tank.
- Function: Serves as a refill source for the watering tank, ensuring a continuous supply of water.
4. Ultrasonic Sensor:
- Location: Inside the watering tank.
- Function: Monitors the water level in the watering tank. When the water level falls below a set threshold, it triggers a pump in the reservoir tank to refill the watering tank.
This system creates a closed-loop irrigation process, making farm management more efficient and sustainable. Let's get started on building it!

WIRE IT!

Start by carefully reviewing the schematics that have been provided. Ensure you have a comprehensive understanding of the layout and connections needed for each component.
- Gather all essential parts as shown in the schematics.
- Start wiring the components by first placing them on your breadboard or PCB layout according to the schematic. Ensure each part is in its proper spot.
- Use suitable wire lengths to connect each component as indicated in the schematics. Pay attention to polarity for parts like diodes and electrolytic capacitors, making sure positive and negative leads are connected correctly.
- Securely solder or attach wires where needed. Double-check all connections to verify they match the schematic exactly, avoiding any wiring mistakes that could cause circuit failure.
- As you finish each part, perform a visual check to catch potential issues early.
- Once all parts are wired properly, proceed to test the connections before powering the circuit to confirm everything works as expected.
BUILD IT!

Please ensure that the components are secured according to the guidelines provided in the image shared earlier. While it's important to reference our method as a starting point, you are not required to replicate it exactly. The primary focus should be on the proper placement and securing of each component to ensure stability and functionality. Feel free to use your creativity and problem-solving skills to achieve this, as long as the end result meets the criteria of being well-organized and secure. Remember, a tidy and secure setup is vital for the overall performance, so take your time to assess the best approach before finalizing the arrangement.
PROGRAM IT!

SCALE IT AND USE IT!
