Automatic Irrigation System DIY Experiments Science Project Model STEM KIT (Assembled), 100% Tested

Please Note we are only providing kit we marked as ACTUAL PRODUCT, project shown customer needs to do at there own we just provide reference.

Overview:
The Automatic Irrigation System DIY Experiments Science STEM KIT (Assembled) provides a hands-on experience in building and understanding irrigation automation. Designed for educational purposes, it incorporates a moisture sensor, comparator IC LM393, and relay to automate the water pump based on soil moisture levels.

Key Features and Benefits:

• Effortless Automation: Automatically detects soil moisture and activates the water pump only when needed.
• Affordable and Simple Design: Uses a standard soil moisture detector probe for cost-effective operation.
• Educational Utility: Ideal for STEM learning, offering a practical approach to understanding circuit building and automation concepts.
• Power-Efficient Operation: Operates on a 5V DC supply, ensuring compatibility with USB power sources.

Applications:

1. Educational projects and STEM activities.
2. Automation of small-scale irrigation systems.
3. Prototype development for robotics and electronics.

Circuit Explanation:

• The system activates the water pump in the absence of soil moisture, thanks to the moisture sensor and comparator IC LM393.
• The relay functions as a switch, controlling the pump based on the detected moisture level.
• Adjust the sensitivity with the variable resistor R2 for customized operation.

Assembly Instructions:

1. Thoroughly review the provided manual, diagrams, and component list.
2. Solder each component to its designated PCB position, ensuring correct polarity for capacitors and diodes.
3. Install IC sockets instead of directly soldering ICs for easier troubleshooting.
4. Test the kit by simulating dry soil conditions to ensure the pump activates as intended.

Components Included:

• Semiconductors: LM393 IC, LEDs, and relay.
• Resistors: Various values, including a 10k variable resistor for sensitivity adjustment.
• Miscellaneous: PCB, pump, USB power cable, and moisture sensor.

Testing Procedure:

1. Connect a 5V DC power source.
2. Introduce water to the soil manually and observe pump behavior.
3. Fine-tune the variable resistor for desired moisture detection intensity.
