基于嵌入式技术的家庭智能呼救系统

本文介绍一种以STM32单片机为核心,通过DHT22温湿度传感器,DYP-me003人体红外感应模块和Mq-2烟雾传感器检测家庭环境信号,由STM32单片机进行处理后发送AT指令控制GSM模块实现发送短信,语音播报,紧急呼救等功能。从而达到防火防盗智能呼救目的的家庭智能呼救系统。

This paper introduces a STM32 single-chip microcomputer as the core, through the DHT22 temperature and humidity sensor, DYP-me003 human body infrared sensor module and Mq-2 smoke sensor to detect the home environment signal, after processing by STM32 microcontroller, send AT command to control GSM module to send SMS, voice broadcast, emergency call and other functions. In order to achieve the purpose of fire prevention and anti-theft intelligent call for help, the family intelligent call for help system.
