Hi Ray,
I’ve worked with the digital DHT11 and the DS18b20 sensors and know how to work with the related libraries and sketches, but what I’m most interested in is seeing examples of how others have specifically done theirs in relation to modifying the Opensprinkler code. I’ve downloaded the latest version from (https://github.com/rayshobby/opensprinkler) and have viewed it, but just haven’t taken the next step of trying to modify it much “yet”…
I have done research / testing with these sensors (DHT11 and the DS18b20 in addition to other sensor / devices) from a stand alone Arduino Uno via the IDE program serial output and will do more once I receive an LCD screen and Ethernet shield that I have ordered. I previously ordered a cheap W5100 based ethernet shield off ebay, but unfortunately haven’t been able to get it to work correctly after trying multiple libraries and example sketches (to help minimize the possibility of some unknown incompatibility issue or a mistake on my part) so there is a chance that it could just be a dud even though the link lights and such appear to work. As mentioned, I have ordered another mid priced one from a vendor that is supposed to be US based and therefore not take 3+ weeks to receive which is normal for the numerous over seas vendors plastered all over ebay and Amazon selling Arduino related products….
Any tips, code examples, forum thread links, etc. that you or others could share would be greatly appreciated.
Thanks
Hello,
Does anyone have any additional tips for adding temperature sensors?
I know how to do this with a stand alone Arduino Uno and hard wiring sensor(s) to the Opensprinkler board shouldn’t be too difficult (I’ve utilized the onboard NO relay contacts to control my garage door, which was relatively easy to do), but any tips or forum threads on the topic would be very helpful. I’m especially interested in how individuals modified the sketches to display temperature(s) on the LCD display and via web page.
I have been using two programs on my Opensprinkler (f/w ver 2.1.1) without trouble since I assembled my DIY kit and put it in use about a month ago. However, when I added a third program today it seemed to trigger the same problem described here.
When attempting to save a 3rd program, it would become duplicated (might be another bug) adding a 3rd and 4th program, but when I went back and deleted the 4th duplicate program I started having trouble not being able to login anymore… I know the updated firmware should now correct this problem and I will update it again soon, but I temporarily corrected this issue by deleting the third program via entering the following in a web browser address bar “http://os-ip/dp?pw=opendoor&pid=2” . This is explained in the “Firmware 2.1.1 API Document” in section 13.
I am reporting my experience with this trouble so that the software can be refined as needed to be improved / more trouble free and also help others that may encounter the same trouble. So far I enjoy using the product and plan to soon connect it to my garage door opener as a way to remotely control it in addition controlling a koi pond fish feeder, an air line valve feeding a skimmer air stone (keep floating pellets out of the skimmer), and a Multi-cyclone MC50 waste water purge valve that are currently being controlled via individual timers and relays. As you can tell, I plan to use it for much more than just controlling my sprinkler system and look forward getting these things mentioned working with it.
