Air pressure sensor and electronic cigarette

The utility model discloses an air pressure sensor and an electronic cigarette. The air pressure sensor comprises a circuit board, a signal processing module, an air pressure sensing element and a control switch, the air pressure sensing element comprises an air flow channel, a vibrating diaphragm and a back polar plate; the control switch is a touchpad, or the control switch comprises a fingerprint sensor assembly, and the signal processing module comprises a fingerprint identification unit; the electronic cigarette comprises an air pressure sensor, a main controller, a battery, an indicating lamp and an atomizer. When the control switch is triggered and the air pressure sensor detects that the air pressure is larger than a preset value, the air pressure sensor sends an electric signal to the main controller to start the electronic cigarette. According to the utility model, the condition of false triggering can be effectively prevented. 本实用新型公开了一种气压传感器及电子烟，气压传感器包括电路板、信号处理模块、气压感应元件以及控制开关；气压感应元件包括空气流道、振膜和背极板；控
