Plastic Water Solenoid...


Plastic Water Solenoid Valve - 12V - 1 / 2 ″ Nominal

12VDC plastic solenoid valve. Normally closed. Liquid can flow in one direction and a minimum pressure of 0.02Mpa (3 PSI) is required. This liquid valve would be a great addition to your robotic gardening project. There are two 1/2 ″ outlets. Normally, the valve is closed. When 12VDC is applied to the two terminals, the valve can be opened and pushed.

F50-12V 10W DC Micro Hydro...


F50-12V 10W DC Micro Hydro Generator

Mini electricity generator, built base on a turbine and an electric generator that converts kinetic energy into electricity. The generator output is rectified and regulated for a maximum of 12V. Please note -if we want to generate more current, the turbine will oppose the greater resistance to the flow of water, and the voltage may drop if the water flow is not sufficient.

This generator is made of plastic and the turbine is totally isolated from the generator and rectifier, the outputs are 1/2 "usually found in domestic pipes.
