Indoor Air-Quality Monitor (CO2, Temperature & Humidity)
Know when it is time to open a window. In tightly sealed winter homes and home offices, carbon dioxide builds up quietly. This monitor tracks it alongside temperature and humidity and shows it on your phone.
This device measures carbon dioxide (CO2). It does not detect carbon monoxide (CO) and is not a substitute for a CO alarm. Delivery takes 7 to 14 business days, usually sooner.
