RIMYI’s vape sensor for airflow control offers precise, low-power airflow detection in compact electronic vaping systems. Designed for high-reliability OEM integration, this sensor circuit ensures accurate airflow recognition through its stepless gear mechanism, supporting consistent vapor delivery with optimal safety.

Smart Capacitance Detection and Control Logic

At the core of this vape sensor for airflow control is the CSC98X circuit. It includes a capacitance measurement unit, a threshold unit, and a PFM output module. This system ensures an adaptive response to real-time airflow changes. The sensor outputs high-level signals when airflow exceeds +8% of the initial capacitance and reaches 100% at +50%. It delivers stable, pulsed output with a 16-ms high-level signal and low-level modulation across 64 grades, supporting smooth power ramp-up in vape systems.

Robust Protection and Energy Efficiency

This compact sensor includes SCP and OTP, preventing system damage from overheating or short circuits. Its low power consumption, below 5uA, makes it ideal for battery-powered vape products. The device also supports long puff protection modes ranging from 5 to 12.5 seconds, helping meet regulatory standards for safety and endurance. You can rely on it to perform consistently in both casual and heavy-use vape applications.

Compact Design, Strong EMI Immunity

With a small footprint of 6mm in diameter and 2.5mm in height, this vape sensor for airflow control easily fits tight spaces in portable vapes. The unit comes with an oil-resistant white protective film for durability. Its strong anti-interference design ensures consistent function even in environments with RF or power noise. You can integrate it with minimal external circuitry, keeping production costs low and efficiency high.

This vape sensor for airflow control provides the intelligent sensing your smart vape devices demand, combining protection, efficiency, and scalability in one compact solution.

sketch

This sensor uses the CSC98X airflow detection circuit with stepless gear sensitivity. It includes a capacitance unit, threshold control, and PFM output with 64 levels. The output is high-level when the capacitance exceeds +8% of the initial value. At +50%, it reaches full output with fixed 16ms pulses. The device consumes less than 5uA and offers SCP, OTP, and configurable puff duration (5–12.5s). Its oil-resistant body is 6mm wide, 2.5mm high, and has strong EMI resistance. It suits cost-efficient, compact vape systems.
