Thanks for the link. I just checked that out and I think I might buy one to test out. Its half of what I want to happen. So thats not bad. I do like how it will allow the valve to turn on when you hit a desired dryness. Edit.What I wish it would do is in addition to turning on when dry it would not turn on if too wet. That way it stays in a range of moisture. Other improvements would be digital control instead of the variable resistor and logic that allowed the sensors to fully control the valves instead of the sprinkler timer. Ie: maybe the plants want water twice a day some days and other days once, or maybe they want water every 14 hrs for the first month and then water every 9 hours the second month. The acceptable range would allow the plants to govern when they wanted water.

I grow in a greenhouse, with beds. The last two years my strawberries have fried out as I’ve been trying to conserve water due to the drought. With so many types of veggies and a hectic schedule stuff just gets watered unevenly.

 

I plan on buying an opensprinkler. Since I am interested in integration with sensors. Is it a wiser decision to buy the pi version as it has a greater chance of being future integrated with sensors?

 

Thanks

 

Edit, after thinking about this for a while I realized my logic was wrong and the feature of turn on if dry does create a range. As buying 1 relay per sensor is still kinda expensive if you scale out, is there a way to build a version of the relay you linked to but with support for more sensors and valves but still one sensor per valve? hmmm

Can you please add in the ability to use sensors (wired or wireless) ? Specifically moister sensors. As well as temp, humidity, light. + data logging

 

Thanks

[Hiouchi John]

Also, I am interested if temp, humidity, and light sensors could be added as well

Thanks

Keep up the good work

Great work Mike, very inspirational.

I’ve been searching for a while for an irrigation controller that also uses moisture sensors. For my needs, I want to have 1 moisture sensor per valve. I really don’t care if I have to run wires, as that is less batteries to replace, however wireless options would be great as well.

I like the direction that you are going with your project, however if I could make a suggestion, with the costs you have detailed above, that it would be fairly costly for me to have 1 sensor per valve. A 10 valve system could be nearly $1000 to automate with your sensors.

(before I found this thread) I had ordered a moisture sensor system from a new startup, plant link. Not sure how well they will work yet as they haven’t arrived but on a cost comparison the wireless sensors are priced at $35 each, though you do need a slightly more expensive base station as well. (and all they do is moisture, no sprinkler control)

 

The moisture sensor that you have chosen looks awesome, however is there a reason that you went with it and not one of the cheaper ones? something like

Is there an easy way to integrate the moisture sensor with wires to the OSPi? and why the pi and not the regular open source sprinkler kit?

I want to buy an open sprinkler however should I go with the regular or pi version?
