Grove - Water Sensor

The Grove Water Sensor is a versatile module that detects the presence of water via exposed PCB traces. When water connects the ground and sensor traces, the circuit is triggered. This straightforward detection method introduces students to conductivity, sensor-based input, and basic environmental sensing.

¢ Educational benefits

• Demonstrates conductivity and resistance principles
• Encourages environmental awareness through water detection
• Provides real-world context for digital input signals
• Builds sensor integration skills in beginner-friendly format
• Useful for developing prototypes with environmental triggers

¢ Classroom ideas

• Build a leak detector or flood alert system
• Test water presence in soil experiments
• Program alerts for when water is detected
• Monitor plant irrigation systems for over-watering
• Create an interactive display triggered by water contact
