Project 22 - IR Trigger Pump "K-12 JUNO STEM KIT"

What You Can Build Using K-12 JUNO STEM KIT

In the "IR Triggered Pump" project from the K-12 JUNO STEM Kit, children assemble a simple automatic water dispenser using a DC pump that activates when an IR (infrared) sensor detects the presence of a hand or a cup. The IR sensor acts as a touchless switch; when something is placed in front of it, the pump powers on and dispenses water. Removing the object turns off the pump, making the system hygienic and hands-free—like the automatic taps in public restrooms.

What You Can Learn

• Infrared Sensing: Kids discover how IR sensors send out invisible light and detect objects by measuring reflected signals.

• Electronic Switching: Learners connect the IR sensor, transistor or relay, and DC water pump, seeing how sensors can automate motors for practical tasks.

• Circuit Construction: Children practice integrating sensors with motors and power supplies, learning the basics of control circuits.

• Real-World Automation: Students understand how their project models touchless dispenser technology used widely for hygiene and convenience.

Real Life Problem Solving

• Troubleshooting: If the pump doesn’t activate, learners examine sensor alignment, wiring, and motor connections, developing step-by-step diagnostic skills.

• Device Understanding: The project demonstrates the workings of automatic hand sanitizers, soap dispensers, and water fountains.

• Design Thinking: Learners may experiment with sensor range or add features (timers, indicators) to improve reliability and efficiency.

Additional Benefits

• Creativity: Students personalize dispenser design, add decorative elements, or create themed applications for events.

• Collaboration: The project encourages group work for assembly, experimenting, and testing.

• Confidence: Successfully automating a pump with a sensor builds electronics mastery and inspires further STEM exploration.

• Foundation for Future Learning: Prepares learners for sensor-integrated systems, robotics, and IoT devices.

Why IR Triggered Pump Matters

The IR Triggered Pump project turns everyday sensor technology into an exciting, hands-on experience, helping kids explore how automation makes the world cleaner and smarter. Each use teaches critical electronics and problem-solving skills in a memorable, practical way.

With Project 22: IR Triggered Pump, every child gets to automate their world—one sensor, one motor, one clean solution at a time!
