Smart thermostat, _DIY Project

Build Status

Salve,

Questo è uno dei miei progetti preferiti. Problema: Accendere il riscaldamento da remoto. Soluzione: Creare un dispositivo connesso in rete che permettesse di azionare la caldaia.

Hi, this is one of my favourite projects. Smart thermostat meaning that you can control your home temperature and heating everywhere. Due funzioni principali / Two principal functions :

Materiale / Materials :

  • Node MCU (Arduino nano wuth built-in esp8266) like this
  • AC to DC 12V like this
  • Temperature sensor like DHT11
  • 2x 1 1kohm 1x 470ohm resistors
  • 5VDC Relay like this

Step by step:

- Stampare supporto 3D / Print 3D support https://github.com/RomeoVir/Remote-thermostat/blob/main/Photos/3D_Printed_Body.jpg
- Verificare dimensioni componentistica / Check hardware dimensions https://github.com/RomeoVir/Remote-thermostat/blob/main/Photos/Hardware_Layout.jpg
  • Caricare software V1_Working su nodeMCU tramite la IDE di Arduino, fare riferimento alla pagina NodeMCU / Write code V1_Working on nodeMCU throught Arduino IDE, use nodeMCU documentation
  • Completare i parametri richiesti / fill the params
//Wifi Configuration
char auth[] = ""; //Blynk auth email code
char ssid[] = ""; //Wifi id
char pass[] = ""; //Wifi password
Collegare hardware / Hardware connections https://github.com/RomeoVir/Remote-thermostat/blob/main/Photos/Hardware_setup.jpg https://github.com/RomeoVir/Remote-thermostat/blob/main/Photos/Diagram_Pinout

Se vuoi puoi aggiungere un led sul pin D3 per segnalazione. If you want you can add a led on pin D3.
