Hi, Yang

This INT terminal is the PAS Sensor's interrupt output signal. (See Table 1 in P4 of the datasheet.)
The INT terminal can be used as an alarm for CO2 concentration.
If you set a CO2 threshold in the internal Register (Alarm _ TH _ H, Alarm _ TH _ L), when the CO2 concentration reaches the set threshold, the INT signal will be set to the active level as an Alarm, and the host MCU can be notified.
*It is recommended to connect to the interrupt terminal of the host MCU.
For detailed functions, see 4.3.3 on page 14 of the data sheet.

Thanks
