Aurora Mini CO2 Monitor DM1305

The Aurora store offers the Dienmern DM1305 for indoor use. Aurora is the storefront; this is the manufacturer’s published model, not an Aurora-designed original. The Dienmern DM1305 is a compact 3-in-1 indoor monitor for carbon dioxide, temperature, and humidity. It uses an NDIR CO2 sensor (400–5000 ppm), lets you adjust the CO2 alarm threshold, and supports display brightness and Celsius or Fahrenheit. A 2000 mAh battery charges over Type-C. The official product photo shows a round white housing with a kickstand, distinct from the square DM1308B. It is a room monitor, not a medical device or smoke alarm.

Best for

Small circular desk or shelf monitor for a bedroom or office when you want a different shape from the DM1308B and an adjustable alarm threshold.
