Features

MEMS Airflow Sensor: The MS6315BS incorporates a highly sensitive MEMS chip that can detect changes in air pressure. This means it can accurately sense the airflow variations during user inhalation and exhalation.
Signal Processing: The airflow changes captured by the sensor are converted into capacitance variation signals, which are then input to an Application-Specific Integrated Circuit (ASIC) for processing. This process makes it easier for the system to analyze and understand the user’s smoking behavior.
User Operation Recognition: By detecting the input capacitance variation signals, the system can recognize user operation behaviors, including inhalation, exhalation, and smoking duration.
Protection Functions: The ASIC chip includes various protection functions to ensure the safety and performance of the electronic cigarette. These functions include protection against prolonged inhalation (up to 10 seconds), over-temperature protection to prevent device overheating, and under-voltage protection in low voltage conditions.
Module Form: The KCP6315BS is designed in a surface-mount technology (SMT) package, forming a module. This allows for direct soldering onto the circuit board, making it highly suitable for PCBA integration, reducing assembly costs, and improving production efficiency.
