Update : The first photo resistor died during the winter after about two year:-( Apparently, they are not really made for outdoor use. Some more pictures as it looks right now. I only had to remove the two top screw holes. Update : OK, a collected order from Digikey included a new case and my LCD display has a final place.

The software is still not at the state wher I would be happy, but I have a working setup, so that will probably move slower now:-( Also, that image shows the info on the display a bit better. Update: I got some blue paint -) So the setup looks a bit more finished now. Now it’s just up to writing/adapting the software to do what I want -)Īs always, it’s good when you can control your own world -) Unfortunately, we don’t have any of the blue wall colour left over, so the footprint of the old sprinkler controller will stay for now:-( I’ll need to get some cable fasteners next time I hit Home Depot. So overall, the bits & pieces work together. So far, I can just get reasonable looking values from it with the Adafruit library😉
I hope to use that eventually in calculating the watering needs. I also added an AM2301 temperature/humidity sensor along with the existing rain sensor. So I control another relay (in the old mechanical timer box) with the included relay. even while the relay is rated for it, I did not like the idea of running mains power into the OpenSprinkler box. So I want to use one channel connected to a photo resistor and the relay to control the lights outside our garage. The OpenSprinkler Pi board (from V1.2, I believe) also includes a 4-channel ADC (8 bit) and an relay. But the extra 16 zones looks like a bit of overkill -) I needed to control 11 sprinkler circuits, so I had to get the Zone Expansion Board. I saw times, when I could not ping the Pi from my laptop but it would answer to pings from the AP (the laptop was used to log into the AP’s web interface, so it could talk just fine to it). But I’m not sure, if it’s the Pi or the access point:-( Something between the two. The WiFi connection is not as reliable as I would have liked:-( So I’ll have to play with that a bit more. Eventually it should also display info about the running/upcoming program & station etc. It currently displays the hostname, the IP address and the current date/time. For now, it’s kept in place by two rubber bands -) I want to use the LCD to display status info. The WiFi dongle is inside the box as indented, but the LCD module did not fit:-( I might look at a higher version of that box eventually. So the current setup consists of the Pi, the OpenSprinkler Pi with a zone extension board, a SainSmart LCD Module For Arduino 20 X 4 with I2C daughter board and an USB WiFi dongle. I have both running here already, so it did not make a big difference -) So I settled on the Raspberry Pi as base-board. When I was ready, the BeagleBone Black was just on it’s way to the revision facelift. And in the end, it came just down to availability.
I liked the `real OS’ setups better than the Arduino-like version. I looked a bit more into OpenSprinkler and especially into the different setups. When I saw Daniel’s setup Garden Automation, I knew that this is a setup I would like -) (Daniel is an organizer/marshal RobotGarden in Livermore, were I hang around once in a while.) We have circuits which would benefit from different patterns, from the normal lawn watering to drip circuits for some flower/veggie beds to some pots and even some soaker-hoses for trees. I was thinking about a more flexible sprinkler controller for a very long time.
