SCHOOL PROJECT SET RAIN SENSOR

A “School Project Set: Rain Sensor” is a model that demonstrates how to detect rainfall using a simple sensor and basic electronics. This project is often used to explain how rain detection systems work in real-world applications, such as automated irrigation, windshield wipers, or weather monitoring.

Concept

The rain sensor detects the presence of water using a conductive surface or probes. When rainwater falls on the sensor, it completes an electrical circuit, which can trigger an action, such as turning on an LED, sounding a buzzer, or activating a motor.

How It Works

1. When rainwater falls on the sensor, it bridges the gaps between the conductive lines.
2. This completes the circuit, allowing current to flow and activating the connected output (e.g., LED or buzzer).
3. The system stops when the water evaporates or is removed.

Educational Value

• Explains the principles of conductivity and circuit completion.
• Demonstrates real-world applications of rain sensors in automation.
• Encourages creativity in designing and implementing sensor-based systems.
