MEMS Airflow Pressure Switch Sensor MS2203AB-M08

MS2203AB-M08 is a MEMS airflow pressure switch sensor suitable for detecting the smoking status of atomizer. When the built-in MEMS chip senses the change of air pressure, the MEMS chip converts the change of air pressure into the change of capacitance, and the MEMS chip is connected to the input of the built-in capacitive airflow detection ASIC chip to determine the user’s operation behavior through the detection of capacitance change signals by the circuit of ASIC input and output the corresponding trigger high and low level signals. The ASIC input circuit detects the capacitance change signal to determine the user’s operation behavior and outputs the corresponding trigger high and low level signals.
