High-Precision Vape Airflow Sensor Board with ASIC Protection

The RM-GDLS60N12-P16 vape airflow sensor board is a compact, high-efficiency component designed for detecting airflow and pressure changes in electronic cigarette systems. It integrates a MEMS sensing unit and an ASIC control chip to ensure accurate, real-time signal output and device safety.

This board features a dual-hole design—one hole on the substrate and another on the circular shell. The shell-side hole senses negative pressure. When the pressure difference across the

MEMS device falls below a set threshold, the GATE pin outputs a high level. If the pressure exceeds the threshold, it switches to a low level. If low pressure persists for over 12 seconds, the sensor enters a protective mode, forcing the GATE to return to low.

Its compact size enables easy integration into portable vape devices. Engineers can benefit from its low power consumption and strong resistance to fluid leakage, oil penetration, and backflow. This makes it ideal for sensitive airflow measurement in limited spaces.

The integrated ASIC chip enhances reliability by offering multiple protection functions. These include prolonged inhalation protection (12s max), over-temperature protection to prevent overheating, and under-voltage protection to maintain system stability during power dips.

The sensor board delivers consistent performance with minimal power draw, making it highly suitable for battery-operated vaping modules. Its precise airflow detection helps improve the vaping experience while safeguarding both the user and the device.

In summary, the vape airflow sensor board provides accurate airflow sensing, robust protection, and compact integration—all essential features for next-generation e-cigarette systems.
