Accurate Airflow Detection

The vape airflow sensor board integrates a MEMS sensing unit with an ASIC control chip. It detects subtle airflow and pressure changes in real time. The dual-hole design captures both substrate and shell-side pressure. When negative pressure drops below the threshold, the GATE pin outputs a high signal. If pressure rises, it switches to low.

Robust Protection Features

Integrated ASIC ensures device safety. It provides prolonged inhalation protection, over-temperature protection, and under-voltage protection. If low pressure lasts over 12 seconds, the sensor activates a protective mode. These functions prevent damage and improve user safety.

Compact and Efficient Integration

Its compact size enables seamless integration into portable vape devices. Engineers can easily fit it into limited spaces. The board offers low power consumption, strong resistance to fluid leakage, oil penetration, and backflow. This makes it ideal for battery-powered e-cigarette systems.

Consistent Performance and Reliability

The sensor delivers stable and consistent signals, ensuring accurate airflow measurements. Its low power draw prolongs device battery life. The high-quality materials and ASIC protections guarantee long-term reliability for high-volume manufacturing.

Ideal for Applications

This board is perfect for OEM vape manufacturers, module integrators, and e-cigarette system designers. Its precision, protection, and compact design make it suitable for next-generation vaping devices, ensuring both safety and performance.
