產品概述

This is an electronic cigarette circuit board that triggers smoking with an airflow sensor and has adjustable power. 它主要由以下電路模塊組成: MCU控制模塊, 動力輸出模塊, digital display, 充電管理模塊, 和鋰電池控制模塊. It can detect smoking actions and control output through MCU, and display smoking status through digital display.

功能亮點

MEMS airflow sensor: The microphone airflow sensor detects changes in air pressure and identifies user smoking behavior.
信號處理: The airflow changes captured by the sensor will be converted into capacitance change signals, which will be processed by the ASIC chip and transmitted to the MCU control module for output control.
保護功能: 該PCBA解決方案板具有多個保護功能，以確保使用過程中的用戶安全, 包括鋰電池保護功能, 吸煙超時保護, 過度保護, 短路保護, 和低電池保護.
模塊形式: SMT包裝用於形成模塊表單, 這使其可以直接焊接到電路上, 使其非常適合PCBA集成, 從而降低組裝成本並提高生產效率.
