MS2102AB-M00 is a MEMS airflow sensor designed to detect the smoking status in atomizer. When the built-in MEMS chip senses pressure changes, it converts these changes into variations in capacitance. The MEMS chip is connected to the input of an external ASIC, which detects these capacitance changes to determine the user’s actions and outputs the corresponding high/low trigger signals.
