2 part question
PART1 - measurement
I am doing a plant watering project, and have already “failed” by starting with the wrong hardware. It turns out that I cannot use the RS21 module with the Hydra board that I ordered, so in order to avoid further mistakes, please advise me if I am on the wrong track:
- I have a moisture sensor
- I’ll have to order a premium mainboard, such as the spider? (why aren’t these boards clearly marked?)
- I’ll be purchasing the RS21 with the intention of:
3.1 obtaining a IP settings from my wireless router
3.2 using http to execute a POST command via the WebClient class in System.Net namespace (i.e.: http://mystuff.windowsazure.com/service/endpoint/takereading?temperrature=27.1&moisture=47.3)
PLEASE let me know if the plan I have is possible using a spider and RS21, I’ve already wasted money on the Hydra following advice from ghi employees whom did not understand what I want to do.
PART2 - acting
For part 2 of this project, I was thinking of adding a pair of ZigBee’s to the same mainboarfd (spyder?) in order to control two valves FROM the cloud, the process goes something like this:
- The Spyder polls a webservice endpoint whenever it has connectivity, no more than once every 15 minutes
- If a watering instruction is found by polling, then the spyder will, via the zigbee’s, activate a different mainboard (my hydra maybe) to first open up one valve to let water inside a dispenser. AFter a few seconds, the first valve closes and the second valve opens, which releases the water in the dispenser to the plant.
I need help with:
- Part number / how to obtain two valves that can open/close like this
- Something I can verify amount of remaining water with
- Check if there is anything else I need to realize this.
The project that I am aims to be as overengineered as humanly possible, that is why I am using cloud services (Azure) as part of the solution. I will also write mobile phone apps for statistics and simple - I realize that I could’ve done this a whole lot easier,however that is not the point
In advance, thanks for reading and for all your comments and suggestions
