On-board Prompt Device Design of No Smoking Based on Clamping Photoelectric Detection

This paper used active infrared detection technology to design a simple and reliable car voice prompt device with high sensitivity, in which infrared transceiver pipes are used for the monitoring of smoke content in the air inside the automotive environment. When someone is smoking, the prompt device can achieve automatic monitoring of cigarette smoke and send voice prompt signal. Furthermore, the circuit of the on-board voice prompt device is illustrated.
