Micro DC hydro generator — compact, selfpowered turbine generator for small electronic devices Overview A compact plastic micro hydro generator that converts flowing water into DC power. Designed for easy assembly into standard household inch water pipes, this unit supplies power without an external source and is suitable for smart faucets, wateractivated sensors, gas water heater controls, and other small electrical devices that require matched DC power. Key benefits Selfpowered operation: Generates DC power directly from water flow, removing the need for batteries or external wiring for many sensor and control applications. Compact and easy to install: Small size and lightweight plastic construction make integration into existing plumbing straightforward. Fits standard household inch pipe dimensions. Stable and efficient: Turbine and motor are closely coupled for energy conversion efficiency and stable output. Low mechanical noise keeps operation discreet. Flexible voltage options: Available output options support common control voltages for a variety of devices. Performance and specifications Output voltage options: 5 V, 12 V, or 80 V Output current: at least 220 mA Output behavior: output voltage without a regulator is proportional to water pressure; use an external regulator if a fixed voltage is required Line resistance: 10.5 +/ 0.5 ohm Insulation resistance: 10 M ohm (measured with DC 100 megohmmeter) Starting water pressure: 0.05 MPa Closed outlet pressure: up to 0.6 MPa Opened outlet pressure: up to 1.2 MPa Axial clearance: 0.2 to 1.0 mm Mechanical noise: no more than 55 dB Physical attributes Color: transparent and yellow Material: plastic Size: approximately 8.8 x 5.8 x 3.9 cm Installation: fits standard household inch water pipe, outer diameter 20 mm, inner diameter 13 mm Mounting base: without mounting base; installation by assembly Applications and use scenarios Touchless faucet power supply: Power sensor modules in automatic faucets so they operate without batteries or wired power. Water heater or boiler control: Provide local DC power for ignition or control electronics in gas water heaters and similar equipment where water flow is available. Sensor or control retrofit: Add to pumps, filtration systems, or offgrid water fixtures to power flow sensors, lowpower controllers, or indicator circuits. Package contents 1 x generator Only the generator is included; other products shown separately are not included. Notes for integration Because the raw output is proportional to water pressure, include a voltage regulator or stabilizer in applications that require a fixed voltage. Confirm pipe dimensions and water pressure at the installation point to ensure operation within the specified starting pressure and maximum outlet pressures. Designed for assembly installation without a mounting base. Ensure axial clearance remains within 0.2 to 1.0 mm for performance. This micro hydro generator offers a compact and practical power source for wateractivated electronics, combining easy installation with efficient energy conversion and low operating noise.
