High-Efficiency Electronic Vape Airflow Sensor for Safe Vaping Systems

The R801AN14-Lxx-OP-150 (±50) PA electronic vape airflow sensor offers high sensitivity, low power use, and advanced safety functions. It is specifically designed for accurate airflow detection in compact vaping devices.

This sensor adopts an ASIC-based architecture, eliminating common MCU failures. It avoids crashes and reset problems due to unstable voltage. The ASIC design ensures a stable and continuous airflow signal in electronic cigarettes.

In power-saving mode, the sensor operates below 5μA static current. This extremely low consumption helps extend battery life in portable vape systems. Its compact design fits perfectly into small e-cigarette structures without adding weight or volume.

The sensor resists air leaks, oil leaks, and backflow, ensuring a reliable measurement of low differential pressures. These characteristics are essential for modern vape designs that demand precise puff detection and a consistent user experience.

It includes multiple on-chip protection features. These include:

Inhalation time limit: Prevents over-inhalation beyond 10 seconds.
Over-temperature protection: Shields devices from heat-related failures.
Undervoltage protection: Triggers when power drops below a safe threshold.

Each protection function plays a key role in maintaining the integrity of the e-cigarette and protecting the user. The sensor’s response speed, precision, and safety make it ideal for vape developers focused on quality.

In conclusion, the electronic vape airflow sensor combines ASIC reliability, low energy use, compact form, and multilayer protection. It is the optimal solution for next-generation, safe, and efficient vaping applications.
