Solenoid Valve to handle CO2

Hi, I want to create a system where if the temperature of the home is higher than a threshold, I want to close the gas with a solenoid valve, I'm thinking to buy this valve: ELETTRO VALVOLA GAS BRAHMA E6G SR10 1/2 BE6 GMO 13762002 REGOLAZIONE PORTATA | eBay

Do you know what I need to create the system:

  1. Arduino
  2. Elettrovalve
  3. Relè
  4. ?

I want to close the gas with a solenoid valve

You heat your house with CO2?

No, the example was for simplicity, I have to create a system for micro algae growth

You will need a means of accurately measuring CO2 concentrations.

My problem is how to handle a solenoid valve with arduino

Use 3) in this list to handle the valve.
