Its so much fun to operate it even my wife loved it immediately. The end user interface is simple and there is an app for all the 3 mobile platforms that matter (iPhone, Android, Windows Phone) The existing valves are in operations since 15 years, they still do their job:Īnd finally a picture of the closed and operational system. The valves are Rainbird 24V AC valves and they worked immediately with opensprinkler.Īs the controller is mounted in a basement i decided to put it into a case i bought and customized, here are some pictures:Ģ.2 ) The holes where i mounted my aluminum barsĢ.3) The complete box with power supply, controller and wiring preparedĢ.4) The system mounted in the basement, wired and operating The sprinkler can control up to 8 valves, i used 6 of it. I ordered it from opensprinkler and welded it on my own, but you can buy also preconfigured devices or addon boards well known IoT devices like the Raspberry PI. That sounds like an advertising message, but i am so happy to get that functionality for that price that i wanted to share some experiences.ġ.) The core element, the sprinkler control system Block all programs for a particular timeframe.Switch on separate valves for particular time frame.See a forecast of programs running in the future.See what programs have been running in the past.Use a free global weather system to influence water amount.Control the device from any place in the world with a network connection.Control the the sprinkler from any device, and i tested:.I replaced my old sprinkler control system Opensprinkler. More video demos showing how to use the controller to switch other devices (light bulbs, power switches etc.) can be found on my website.I have done it and it works better that expected. You can access the controller using any device that has a built. ![]() Compared to traditional sprinkler timers, which limit you to a few buttons, dials, and a small screen, the web provides a much more intuitive user interface. You can follow the design to make your own PCB or simply buy a kit from: Video Demoīelow is a video demo of the project. The OpenSprinkler web interface allows you to program water schedules and monitor station status through the web. The design of the schematic, PCB, and parts list can be found on the project description page at: h ttp:// Most importantly, it comes as an open-source kit, so you can feel free to build it, program it, modify it, or hack it! This project requires some soldering tools and skills, but even if you have never soldered before, it should be pretty easy to get started. The power supply design works with both AC and DC power input. Login : log in with your account name and password. The triacs on board can also be used to switch other AC devices, or replaced with MOSFET/transistors to switch DC devices. Reserved PCB slot for the RFM12B wireless transceiver, useful for wireless RF communications with sensors, battery-operated valves (coming soon), and remote-control units in the future. The controller is compatible with most 24VAC household sprinkler valves. Powered directly from the 24VAC sprinkler transformer. Allows up to 8 water stations/zones, individually controlled (can be extended to 16 by adding a shift register). Microchip ENC28J60 Ethernet controller enables web-based scheduling, through either wired Ethernet connection, or WiFi connection if used with a WiFi repeater. AVR Atmega328 MCU running at 8MHz, compatible with the open-source Arduino software. Basic features of the OpenSprinkler include: These limitations are the main motivation of this project. It is based on the design of OpenSprinkler, but its ‘brain’ is an RPi instead of an AVR microcontroller. ![]() You may be planning to buy or have already purchased a commercial sprinkler timer / controller, but chances are that these systems provide a limited set of fixed functionality, and have no web scheduling capability. OpenSprinkler Pi (OSPi) is an open-source sprinkler / irrigation extension board for Raspberry Pi (RPi). It can be used to schedule and work with standard 24VAC sprinkler valves commonly found in household watering and irrigation systems. I am proud to introduce OpenSprinkler: an open-source, programmable, web-enabled sprinkler valve controller.
