DIY – Water Overflow Alarm Electricity Kit – Tested & Verified (Educational projects and learning DIY kit)

Product Description The DIY Water Overflow Alarm Kit is a "tested and verified" educational project that demonstrates the electrical conductivity of water. By placing two metal probes at different levels in a container, students create an open circuit that only closes when water bridges the gap. Once the water reaches the "overflow" level, the system triggers a loud speaker and a bright LED. This kit is a favorite for school science exhibitions, teaching the principles of liquid sensing and home automation safety.

Key Features

• Real-World Application: Simulates the technology used in industrial overhead tanks to prevent water wastage.

• Dual Feedback System: Combines an audio alarm (speaker) and a visual cue (LED) to ensure the overflow is detected immediately.

• High-Sensitivity Design: Engineered to work with standard tap water, utilizing the natural minerals in the water to complete the circuit.

• Easy Assembly: Features a simplified wiring system (Yellow-to-Yellow wires) that requires no professional tools or soldering.

• STEM Learning Focus: Provides a clear demonstration of how conductive materials and sensors interact to automate mechanical responses.

Technical Details

• Working Principle: One probe is placed at the bottom of the tank and the other at the top. When water touches the upper probe, it completes the path for the current to flow from the battery to the speaker and LED.

• Component Quality: Features high-quality nuts as probes to resist immediate corrosion and ensure a stable connection.

• Portability: Powered by a 9V battery, making it safe for use around water in a classroom setting.
