Precision-Engineered for Smart Airflow Detection

Our custom vape airflow sensors deliver precise airflow monitoring for today’s advanced vaping devices. They use cutting-edge MEMS technology. Moreover, we designed them with a dual-hole structure to enhance accuracy in negative pressure detection.

Innovative Dual-Hole Design

Each sensor includes one air hole on the substrate and one on the shell. The shell hole receives negative pressure directly. When pressure across the MEMS unit exceeds the threshold, the GATE output quickly shifts from high to low. If the pressure remains low for 12 seconds, the sensor activates protection and keeps the GATE output low.

Compact and Reliable Structure

We engineered the sensor to be compact and energy-efficient for easy integration into portable vape devices. Furthermore, its leak-proof, oil-resistant film ensures stable operation even in vapor-rich environments. It also blocks backflow effectively, reducing false triggers and avoiding internal damage from fluid intrusion.

Multi-Layer Safety Protections

We embedded an ASIC chip to improve device safety with multiple protective features. These include 12-second-long inhalation protection to limit extended puffs and maintain safe operation. Additionally, over-temperature protection prevents the sensor from overheating during frequent use. Under-voltage protection keeps the sensor working reliably even when battery levels drop.

Ideal for Slim, Portable Designs

Thanks to its small size, this sensor fits easily into slim vape enclosures without compromising functionality.
Its high-sensitivity differential pressure detection ensures accurate airflow control in compact, battery-powered devices.

Built for Durable, Accurate Performance

We designed the sensor to meet the tough demands of modern e-cigarette manufacturing.
It offers consistent quality and durability through every production batch.
Moreover, our testing process ensures each unit meets strict accuracy and reliability standards.

Conclusion: A Smart Solution for Safer Vaping

In summary, our vape airflow sensors offer smart design, strong protection, and dependable performance.
They help manufacturers build safer, smarter, and more user-friendly vaping solutions.
