By the end of this lesson, you will be able to:
- Understand how sensors make IoT smart.
Answer: Sensors collect data from the environment and allow IoT devices to respond intelligently. - Learn about temperature and soil moisture sensors.
Answer: Temperature sensors detect heat levels, and soil moisture sensors detect dryness/wetness of soil. - Build an IoT-based alert/monitor system.
Answer: By connecting sensors to Arduino + IoT dashboard, students can monitor live values and trigger actions (like alerts or pumps).
