NeevCraft Automatic Touchless Water Tap DIY Working Model Kit with IR Proximity Sensor & Relay Module for Science Fair & School Projects

Promote water conservation and smart hygiene with the NeevCraft Automatic Touchless Water Tap DIY Working Science Project Kit. Thoughtfully created by NeevCraft, this practical hands-on STEM project demonstrates the technology behind modern sensor taps and touchless automated sanitation systems used in airports, hospitals, and smart homes. The working principle is smart, clean, and simple: when hands are placed beneath the spout, the integrated high-precision Infrared (IR) proximity sensor instantly detects motion and triggers the 5V relay module. The relay acts as an electronic switch to power the DC submersible water pump, dispensing water automatically. As soon as hands are removed, the water flow stops immediately, effectively preventing water wastage and cross-contamination. Built on a sturdy base with a clean PVC pipe structure, breadboard power-rail, and clear tubing, this kit is completely solderless and straightforward to assemble. Whether you are presenting at a school science fair, competing in INSPIRE Awards, or teaching kids practical automation and sensor circuits, NeevCraft provides a complete, reliable, and high-scoring working model. Key Features & Highlights 100% Touchless Operation: Uses an active IR sensor module to detect hand placement and automatically dispense water without turning any physical valve. Water Conservation Concept: Demonstrates the essential theme of "Save Water, Save Life" by cutting off flow the second hands move away. Easy Solderless Assembly: Designed with jumper wires and a mini distribution board for quick, mess-free connection—perfect for students and young makers. Reliable Relay-Driven Switching: Features an onboard relay module with LED indicator status that safely isolates the control signal from the pump power. Compact Submersible Pump: Low-noise, energy-efficient DC submersible pump delivers steady water flow through transparent food-grade tubing.
