婴儿安全预警系统采用单片机AT89C51为主控芯片。完成婴儿室内温湿度、烟尘等参数的显示及其报警设计。主控芯片负责对传感器采集来的周围环境的温湿度、烟尘浓度的信号进行处理,并由液晶显示器显示当前温度值和烟尘浓度等信息。一旦婴儿周围环境恶化,如温度过高、过低或烟尘浓度超标,将启动系统的声光报警装置,同时系统还会将当前状况通过蓝牙的形式告知家长,以求迅速及时处理。
Baby safety early warning system using microcontroller AT89C51 as the main control chip. Complete the baby indoor temperature and humidity, smoke and other parameters of the display and alarm design. The main control chip is responsible for the sensor to collect the ambient temperature and humidity, soot concentration signal processing, and by the liquid crystal display displays the current temperature and soot concentration and other information. Once the baby’s surroundings deteriorate, such as over-temperature, over-low or excessive concentration of smoke and dust, the system will start the sound and light alarm device, at the same time, the system will inform the parents of the current situation in the form of Bluetooth in order to promptly and promptly handle it.
