Smart Disposable E-Cigarette Circuit Board with Airflow Sensor
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.
Functional Highlights
- MEMS Датчик воздушного потока: The microphone airflow sensor detects changes in air pressure and identifies user smoking behavior.
- Signal processing: 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.
- Protection function: This disposable e-cigarette circuit board includes multiple protection features to ensure user safety. It provides lithium battery protection, smoking timeout protection, over-temperature protection, short circuit protection, and low battery protection. 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.
