The SD card has also pre-installed Samer’s mobile web app, which provides a nice front-end for mobile devices such as pads and phones. The details are all explained in the user manual of the interval program. The interval program has a rich set of software features, such as setting multiple sprinkler programs, preview programs, run-once program, manual operation, logging, rain delay etc. This will bring up the interval program’s web interface. As soon as the system has booted and is up online, you can open a browser and type in (where x.x.x.x is your BeagleBone’s IP address). The pre-configured SD card runs a Ubuntu operation system (default user name ubuntu, password temppwd), and sets Dan’s interval_program to start by default. Download the image, burn it to a microSD card, pop it in to your BeagleBone Black, and you are ready to go. Specifically, I’ve created a SD card image with pre-installed software. Software Setupįollow the recent update on OpenSprinkler Pi, the software setup for OSBo has also been made a lot easier. If you have a rain/freeze sensor, you can connect it to the rain sensor terminal.

The interface is the same with other sprinkler controllers. Plug in the BeagleBone Black into OSBo, connect the 24VAC power, plug in the common (COM) wire and individual station wires, and that’s it. The board makes use of the first 2×10 pins on port P9 of the BeagleBone Black for interfacing with shift register, RTC, rain sensor port, and mini-relay.

In addition, you need to provide a BeagleBone Black, a nano-size WiFi dongle, and a 24VAC sprinkler transformer (these are not included in the kit and need to be purchased separately).

The kit comes with an assembled OpenSprinkler Beagle circuit board, enclosure, screws, terminal blocks, and extra pin headers in case you want to map out additional GPIO pins. For details, please watch the tutorial video above, and visit the official OSBo homepage at. Added a rain sensor port with pull-up and current limiting resistors.īelow is an annotated diagram that shows the various components of the board:īelow I am going to give a very brief overview of the hardware and software setups.There is also a solder-on 2A fuse on the 24VAC line. This helps prevent incorrect connection to other terminal ports. The 24VAC terminal block is changed to orange color with 3.96mm pin spacing.It can be used for switching low-power lighting, or garage doors etc. The relay has a contact rating of 120VAC / 2A. Added a 5V mini-relay for more general-purpose switching.The BeagleBone Black is now plugged down into OSBo, and all GPIO pins are mapped out to the pinout area.Added a total of 10 bidirectional TVS for protection against transient voltages: one for each of the eight stations, one for the 24VAC port, and one for the rain sensor port.But it also offers several improvements, specifically: It also currently shares the same enclosure as OpenSprinkler Pi. The hardware design of OpenSprinkler Beagle is similar to OpenSprinkler Pi: it contains a 24VAC to 5VDC switching regulator, shift register, triac, DS1307 RTC with CR1220 battery, zone expansion board connector. Undoubtedly it makes sense to develop an OpenSprinkler variant for the BeagleBone Black. both are low-cost embedded Linux boards), it offers some interesting benefits such as a large number of GPIO pins, build-in analog pins, build-in eMMC, microSD card slot (i.e. While the BeagleBone Black is similar in nature to the Raspberry Pi (i.e. Over time I’ve received requests from users to develop a similar board for the BeagleBone Black. Since OpenSprinkler Pi was released earlier this year, it has been a very popular product. The idea of OpenSprinkler Beagle came from the OpenSprinkler Pi, which is a sprinkler extension board for the Raspberry Pi. Best of all, it’s an open-source project - you are welcome to tinker with the hardware and/or software to create your own customized sprinkler controller. You can use online weather data to help regulate sprinkler water time, and remotely change settings and programs when you are traveling away. Using this board, you can easily convert your BeagleBone Black into a low-cost, web-connected smart sprinkler controller. It uses four GPIO pins to control an unlimited number of sprinkler valves. OpenSprinkler Beagle kit is available for purchase at Rayshobby Shop.įollowing the sneak-peak preview, I am excited to announce that OpenSprinkler Beagle (OSBo) v1.0 is now officially released! OpenSprinkler Beagle is an open-source sprinkler / irrigation extension board for the BeagleBone Black.
