This precision airflow sensor module for vape systems is engineered for demanding low-pressure environments. It uses a robust ASIC design to eliminate crashes common with standard MCU-based systems. The chip resists resets caused by voltage drops below critical levels, ensuring constant operation and enhanced product reliability.

Ultra-Low Power, Compact Design

With a static current under 5μA in sleep mode, this module saves battery life while maintaining responsive detection. Its compact structure suits space-limited vape devices. It offers leak-proof and oil-resistant features. The sensor’s build prevents backflow, ensuring clean airflow measurement in high-humidity and vapor-heavy environments.

Optimized for Portable Vape Applications

The precision airflow sensor module for vape excels at detecting minimal pressure differences, making it ideal for portable e-cigarette products. It accurately tracks air input to trigger vaporization at the correct moment. This real-time sensitivity allows brands to deliver smooth and consistent vapor production.

Built-in Safety and System Protections

The ASIC chip integrates key protections including 10-second prolonged inhalation limits, over-temperature cutoff, and under-voltage response. These functions prevent overuse, overheating, and system failure. The intelligent control ensures safe operation without affecting vaping performance.

Efficient, Stable, and Reliable

Engineers can easily integrate this precision airflow sensor module for vape into smart control boards or sensor modules. It reduces development time while ensuring consistent airflow detection across device lifecycles. Whether you’re developing entry-level pens or advanced pod systems, this sensor provides a professional-grade airflow solution.
