This disposable e-cigarette circuit board uses an airflow sensor to trigger smoking and supports adjustable power output. It integrates an MCU control module, power output, digital display, charging management, and lithium battery control. The airflow sensor detects each puff and signals the MCU to control power output precisely. The digital display shows real-time smoking status, helping users track usage clearly and efficiently.

功能亮點

MEMS airflow sensor: The microphone airflow sensor detects changes in air pressure and identifies user smoking behavior.
信號處理: The sensor captures airflow changes and converts them into capacitance change signals. The ASIC chip processes these signals and sends them to the MCU control module for output control. This process ensures the efficient operation of the disposable e-cigarette circuit board.
保護功能: This disposable e-cigarette circuit board includes multiple protection features to ensure user safety. It provides lithium battery protection, 吸煙超時保護, over-temperature protection, 短路保護, 和低電池保護. These safety functions work together to deliver a secure and reliable vaping experience.
Disposable E-Cigarette Circuit Board Module: The disposable e-cigarette circuit board uses SMT packaging for module formation. This allows direct soldering onto the circuit, ideal for PCBA integration. The result is reduced assembly costs and improved production efficiency.
