In general, the task that stands before me is described in the title, now I will describe how I see the process:
1. Computer - at the moment normal, ideally Arduino.
2. Electrovalve (for turning off / on the water supply)
3. Power glass (for opening the windows of the greenhouse), I think to take a simple car.
4. Battery - I don’t know what to take under this case at all, I don’t know if the car is suitable.
5. Somehow insert a gsm module into this case (3g modem as an option).

Well, in general, that's all, that is, the scheme of work sent SMS with one code, water flowed, stopped with another, etc. Then it will be possible to stick temperature sensors and similar prikolyukhs! But I would like to get info from experienced people, how to organize all this. Thank you in advance!

  • IMHO, arduino - pampering. if the smart home does not end on a greenhouse, then the system should be built on something more serious. if you bring the project to completion, it would be interesting to hear what and how you did it. - Yura Ivanov
  • @Yura Ivanov, just in the middle of the garden it would be easier to locate and shelter from moisture and heat than a regular computer. - Artur Panteleev
  • @ Arthur Panteleev, well, there are wireless systems that wouldn’t have to be covered. In any case, this or that implementation deserves attention. About Arduino, this is me from my bell tower - IMHO. - Yura Ivanov

Raspberry PI2 and Arduino + gsm module + powerRalayPad (if the current is high).

According to the simple-microcomputer Rasperry Pi2 (it matches with arduine, there are many different examples in the public domain), your arduino (it’s quite simple in the part of writing code for it). There is a gsm module for arduin too, and there are examples of working with it and working with the commands adopted. PowerRelyaPad is nothing more than the control of relay power. If my memory does not fail me, then this is for working with 220v. I admit that my knowledge of the output control boards is somewhat outdated, but I remember that there is an output control board, i.e. essentially power supply to your lifts.

And immediately solve the task of updating the window position because The likelihood that ESP breaks down exists. Look toward the reed switch or something like an alarm on the windows.

Why so far it is better to use arduino - ease of writing and availability of both examples and components. What you end up with will be a prototype, on the basis of which you will be able to execute the implementation on more correct components in terms of fault tolerance.

    I foresee problems with the GSM- module. The reliability of the GSM- module entirely in the power of the cellular operator. Therefore, I would do so. I connected to the mobile Internet through a router. And already connected to the router Arduino via WiFi- shild. On the Arduine, a Web client is spinning, which contacts the server once every 5 minutes, transferring data from the humidity sensor (after all, if the humidity is high, then watering is not required). And the server is already responding, whether to water or not. This is so that you can set the watering parameters on the server through a convenient web interface.

      Arduino + Shield Relay + Analog Moisture Meter + Light Sensor and Temperature 2 pcs. Essence to avoid human interference (GSM) logic. Measure the temperature inside. Open the window below. If the night and the temperature below the window are lower and in the greenhouse, too. moisture - the principle of dry pour wet not pour

      • Yes, and about the reed switches also do not interfere - Timur Mirhaydarov
