Interested in learning more? You can check out OSBee here and the OSBee Arduino shield here. Indeed, the OSBee Arduino library offers at least one example of using the Arduino Ethernet shield with OSBee shield to create a web interface for sprinkler control. While the OSBee shield itself is not equipped with built-in wireless modules, Makers and devs can stack it with other Arduino shields, such as RF, WiFi, Ethernet shields, to provide web connectivity. “The other OpenSprinkler products, such as OpenSprinkler 2.1s, DIY 2.1u, OSPi 1.4, OSBo 1.0, are all designed for 24V AC sprinkler valves, which operate on 24V AC and require a power adapter / transformer.” So it’s very efficient and suitable for battery-operated controllers,” said Ray. These valves internally use a latching solenoid, which only draws power when you open or close the valve, and does not draw power if it remains in the same state. “The main difference is that OSBee is designed to work with battery-operated sprinkler Tvalves. So, how does the OpenSprinkler Bee (OSBee) differ from other OpenSprinkler products? Different from the classic OpenSprinkler, OSBee now comes with a water-proof enclosure, which means it can be left outdoors, such as in a garden, and will do its work diligently, like a Bee.”Īlthough the OSBee itself is still in the prototype stage, Ray recently debut the OSBee Arduino Shield (V 1.0), which is currently available for purchase. For Security+ 2.0 systems (which has a yellow learn button), you will need to buy a Security+ 2.0 adapter as an add-on. OpenGarage works with most garage door systems. It has built-in WiFi, cloud support, and automation feature. “Also, ‘Bee’ reminds me of the garden, and gardens need to be watered, so, there is the connection. OpenGarage is an open-source, universal garage door opener. It may very well have an XBee slot in the end, but the name was not intended to imply XBee,” Ray of explained in a blog post. It’s coincidence that it sounded more like XBee. “The name ‘Bee’ comes from the abbreviation Battery-Enabled Extension. Recently debuted by RaysHobby, the platform is powered by an ATmega328 microcontroller (MCU) paired with a nRF24L01 2.4G RF transceiver.Īdditional key components include two AA batteries (boosted to 3.3V), SMT buzzer, push-button, 16KB EEPROM, PWM-driven boost converter, H-bridge (to drive sprinkler solenoid), soil moisture sensor and a Serpac 121 enclosure with water-proof perimeter seal. Does it make sense to try to make my own or should I just pay the money and get an OpenSprinkler Pi? I don’t exactly have lots of free time either.The OpenSprinklerBee (OSBee) is an open-source Atmel-based sprinkler timer (prototype) designed to work with battery-operated valves. I looked in the forums and I can’t really tell if this is something that people talk about on the forum or if they’re pretty much on their own if they do this. The only reason I think I might be able to make something is that there are so many webpages of people using OpenSprinkler with their own custom builds and they only use a few parts (mainly the microcontroller and the relays). I’d rather use the ESP boards because I’m not sure I’ll ever use them for anything else and I’ve already used the Raspberry Pi for a few things (mainly retropi). My electrical engineering knowledge is pretty basic, like I understand the ideas but I’ve never designed anything. The microcontrollers were given to me as part of conference badges years ago and I bought the other stuff thinking I’d do something with the microcontrollers but I never did. I have 5 zones but someday I might want to add more (like for a garden). My sprinkler valves are 24V AC and my old sprinkler controller has a 24V AC transformer. I’m mainly missing the relays and I don’t have a 24V AC to 5V DC converter (and not sure I want to try to make one, although I might buy something instead of putting a 5V adapter in my outdoor container). I have a Raspberry Pi Zero W, 2 x WeMos D1 mini (ESP-8266), 2 x Lolin D32 (ESP32-WROOM-32), a SparkFun RedBoard (ATmega328), and a box full of other parts (shift registers, resistors, buttons, transistors, MOSFETS, voltage regulators, I think a humidity and barometric pressure sensor too, etc). I know Ray makes money selling prebuild controllers but I guess I’m trying to save a few bucks and use what I already have. I went looking online and I found OpenSprinkler. My commercial sprinkler controller quit working so I decided to see if I can make something with all the spare parts I have before I buy a new controller.
