Customer:
I’m interested in building a logic system to monitor and control a house heating system and display it on a monitor or tablet. To start with, roughly ten thermal sensors that would show the current temperature state in the boiler, storage tank, flow and return water. I’m interested in what you would recommend to start with? The next step would be adding a solar system, i.e. panels and their integration into the system.

zanima me samogradnja logičkog sustava koji bi nadgledao i kontrolirao sustav grijanja kuće i to prikazivao na monitoru ili tabletu. Za početak otprilike nekih desetak toplinskih senzora koji bi prikazivali trenutno stanje temperature u kotlu, spremniku, polaznom i povratnom vodu. Zanima me što bi mi savjetovali s čim početi? Slijedći korak bi bio dodavanje solarnog sustava, odnosno ploča i njihovo uklapanje u sustav.

I’m assuming you’d connect all the sensors with wires to one controller, as you mention you’d run it from solar panels? In that case we recommend a Croduino microcontroller and a display of your choice. For temperature sensors we recommend Dallas DS18B20. You only need 3 wires to connect them in a system where Croduino collects the data. After that you can display the data on a screen of your choice or send it to the cloud (internet database). To control devices use relays - we recommend SSR relays. You can send data to a tablet via a Bluetooth module, but it’s not recommended due to limited range. It would definitely be better to connect it to the network, create an API and connect to devices. In some order:
- Select basic components
- Connect sensors to the microcontroller
- Determine relay control conditions (I don’t know if you want this part, or just want to monitor temperature)
- Data display

pretpostavljam da bi žicama povezali sve senzore na jedn akontroler, jer kažete da bi ga pokretali preko solarnih panela?
U tom slučaju preporučujemo Croduino mikrokontroler i display po izboru. Senzore temperature preporučamo dalasove DS18B20. Dovoljne su Vam 3-žice da ih povežete u sustav, u kojem Croduino prikuplja podatke. Nakon toga podatke možete prikazati na ekranu kojeg izaberete ili poslati na cloud(internet bazu podataka). Za upravljanje s uređajima koristite releje, preporučujemo SSR releje.
Na tablet podatke možete poslati pomoću bluetooth modula, nije preporuka zbog malog dometa. Svakako bi bilo bolje povezati ga na net, napraviti API i povezivati na uređaje.
Nekim redom:
-
Odabrati osnovne komponente
-
Povezati senzore na mikrokontroler
-
Odrediti uvjete kontrole rejela (ne znam želite li ovaj dio, ili samo želite pratiti temperaturu)
-
Prikaz podataka
