Full Product Description

Harness the Power of Water for Your DIY Projects

Turn everyday water flow into a reliable power source. The DC Water Flow Generator is a highly efficient micro hydro turbine designed to integrate seamlessly into standard 1/2" (4分) plumbing systems. As water flows through the transparent casing, it spins the internal turbine, generating clean DC electricity. Whether you are building an automated smart garden, a self-powered water meter, or an educational STEM exhibit, this generator provides the off-grid power you need.

Stable 5V or 12V Regulated Output

Unregulated generators can fry sensitive electronics with voltage spikes. We offer this generator in two specific models with built-in voltage regulation circuits:

  • 5V Regulated Output: Perfect for directly charging mobile phones, powering Arduino/Raspberry Pi boards, or feeding into lithium battery charge management chips.
  • 12V Regulated Output: Ideal for powering 12V LED lighting strips, 12V radios, or small 12V water valves and relays. (Note: Peak current for the 12V model is approximately 100mA).

Low Starting Pressure & High Durability

You don't need a roaring waterfall to generate power. This turbine features a highly sensitive design with a starting water pressure of just 0.05Mpa. It is built to last, boasting a mechanical lifespan of over 3,000 hours and operating quietly at under 55dB. The robust casing can withstand closed peak pressures of 0.6Mpa and opening peak pressures up to 1.2Mpa, ensuring it won't burst under standard municipal water pressure.

💡 Pro Tip from Our Technicians

"When installing this micro hydro generator, pay close attention to the directional arrow on the transparent casing—water must flow in this exact direction to spin the turbine correctly! Also, remember that the output current depends heavily on your water pressure. If you're building an off-grid IoT water meter and need help regulating the power to charge a Li-Po battery for an ESP32, drop by our Sham Shui Po store! Our team at Sun Cheong Computer Co. Ltd. can help you select the right charge management chips and wiring for your DIY project."

FAQ Section

  • Can I use the 5V water flow generator to charge a smartphone directly?Yes, the 5V model features a regulated output circuit that provides a stable 5V DC, which can be used to charge mobile phones or power USB devices. However, please note that the charging speed will depend entirely on your water pressure and the resulting current (mA) generated.
  • What is the minimum water pressure required to start generating electricity?This micro hydro turbine is highly sensitive and requires a starting water pressure of only 0.05Mpa to begin spinning and generating power. This makes it suitable for many standard household taps and gravity-fed irrigation systems.
  • How do I connect the 2-pin terminal to my Arduino or IoT project?The generator comes with a standard 2-pin connector (Red for Positive VCC, Black for Negative GND). You can easily splice these wires or use jumper cables to connect them directly to the VIN/5V pin of your Arduino, or into a lithium battery charge management module for energy storage.

Target Users / Applications

  • Off-Grid IoT Developers: Powering remote water flow meters or smart agriculture sensors where solar power is unavailable.
  • Smart Irrigation DIYers: Creating self-powered automated sprinkler systems that charge their own batteries when the water flows.
  • STEM Educators & Students: Demonstrating the principles of hydroelectric power conversion in science fairs and physics classrooms.
  • RV & Campervan Builders: Harvesting energy from onboard water pumps to trickle-charge small 12V LED lighting systems.
