■ Key Evaluation Points by 'Kaden Hihyo'

In the magazine, five air quality monitor products aimed at improving indoor environments were subjected to a comparative review regarding CO2 concentration, temperature, and humidity measurement accuracy, as well as app operability and installation flexibility. The "SwitchBot CO2 Sensor" particularly stood out for its user interface's ease of use and superior connectivity with other devices, earning a comprehensive score of 57.8 points (out of 70) and being selected as the Best Buy in its category.

  • Excellent Visibility and Intuitive App Operation: High praise was given to the product's large LCD display for easy information viewing, along with the app's ability to show six items, including CO2, temperature, and humidity, in a single list. The graphing function for past data makes it easy to grasp trends in environmental changes.

  • Automated Environmental Improvement through Smart Home Integration: The ability to build practical automations, such as automatically activating a circulator or air purifier in response to rising CO2 levels by linking with SwitchBot Hub products (sold separately), was recognized as added value beyond just a sensor.

  • Flexible Installation: The device supports USB-C power supply and can also be powered by two AA batteries, allowing for cord-free wall mounting and other flexible installation options to suit various living environments, which was deemed practical.
