The Water Detector Engineering Kit is a solderless breadboard circuit that uses a 555 timer IC to sound a tone when it senses water or moisture. It comes with the breadboard, components, schematic and breadboard layout. You will need jumper wire to assemble it and a 9V battery to power it.
Key Features
- Sounds a tone when water or moisture is detected
- Built around a 555 timer IC
- Solderless breadboard: no soldering required
- Schematic and breadboard layout included

Frequently Asked Questions
Are step-by-step instructions included?
No. The kit includes a parts list and a circuit diagram; you identify the parts and place them on the breadboard following the diagram.
How does it detect water?
Water bridging the sensing contacts completes the circuit, which lets the 555 timer generate a tone.
What jumper wire do I need?
Solid jumper wire between 21 and 26 AWG fits the breadboard. Jumper wire is not included.
