[Alert Notification Function & Remote Confirmation] Three types of alerts: ``warning sound on the main unit, blinking numerical value on the display, and app notification*'' notify you of changes in CO2 concentration. You can check the CO2 concentration in your room even when you are away from home, and the ventilation alarm lets you know when to ventilate immediately. *SwitchBot hub product required [Equipped with NDIR method CO2 sensor and Swiss-made temperature and humidity sensor] Adopts NDIR method CO2 sensor recommended by the Ministry of Health, Labor and Welfare to provide highly accurate air quality data. The Ministry of Health, Labor and Welfare recommends that the carbon dioxide concentration be below 1,000 ppm in order to maintain good indoor ventilation. Furthermore, it is equipped with a highly reliable and highly accurate temperature and humidity sensor that always provides the latest and accurate data. [2WAY power supply] Both battery and Type-C power supply are OK! With Type-C power supply, you don't have to worry about power outages and data is updated every second.

Visualize data by displaying graphs of changes in CO2 concentration, temperature, and humidity. Data (CSV file) can also be exported, allowing you to check the history of CO2 concentration, temperature, and humidity. [Check temperature and humidity with voice] If you link it with a smart speaker such as Alexa or Google Assistant, you can conveniently check the temperature and humidity even when you can't take your hands off it just by saying, "Alexa, tell me the temperature." . *The CO2 concentration confirmation function is currently under review by the Amazon Alexa team and is not available at this time. [Interlocking with SwitchBot devices] When linked with SwitchBot hub products and smart circulators, the circulator will automatically turn on and off to provide ventilation when the CO2 concentration exceeds or falls below a pre-specified comfortable value.
