Drip Irrigation Kit(K10): Lesson0

Overview

The course follows the logical thread of "Sensor Basics - Design and Creation".

The Sensor Basics section (Lessons 1-4) adopts a "thematic inquiry" model, allowing students to master skills such as sensor application and simple programming in the process of exploring various small themes.
The Design and Creation section(Lessons 5-6) is set against the backdrop of UN Sustainable Development Goal 15 (Life on Land). It guides students to focus on protecting land life, conduct research on methods, determine solutions, and engage in hands-on design, building, coding, and decoration, ultimately completing a full rainwater collection and drip irrigation system.

Learning goals

Identify the relevant components of the UNIHIKER K10 and learn basic operations and connections.
Explore how sensors and actuators work, including Water Level Sensor, Soil Moisture Sensor and water pump.
Get to know SDG Goal 15 (Life on Land) and describe how this device protects and restores life on land.
Design, build and test a drip irrigation system that uses collected rainwater.
