Inquiry About air quality control system2019-07-09 18:37:03
Air intelligent controller (KF-800F)
Which sensor does it have? I need lov voltage power supply (security or 5 V DC or 12 V DC). Can I open the box, where should I connect 5 V to this device? Or where can I give it another lov voltage power supply? Could you please ask an engineer? I need to use it for example in a car (there is not 220 V power supply), only 5 V form power bank or 12 V from battery? Could you please send a link to a film (avi? mov?... youtube?) where there is increase of CO2 value shoving the Alarm ON and sound level compared to voice? You can speak your language and this device should start to give us this information, alarm. Or I must connect my alarm system to the realy, and I will receive the relay open when CO2 level is above for example 800 ppm? Sincerely, And
