If you are considering the addition of a flow sensor to your watering system, then you should also consider adding this brass solenoid valve from Adafruit. Just like the flow
sensor, most of this fitting is made of brass for added durability. Now you can easily turn your water source on and off via your Raspberry Pi or microcontroller.
Just keep in mind, unlike many other sensors and components used in DIY electronics that run on 3.3 V or 5 V, this one operates on 12 volts. There are also some other important considerations before choosing a solenoid valve, so head over to the website for more information and to see if this is a good choice for your project.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
