摘要
为更好地照顾婴儿,分担新爸爸新妈妈的负担,提出一种基于MSP430单片机的婴儿睡眠监护系统。系统包括多点尿湿检测模块、声音检测模块、声光报警模块和无线传输模块。以低功耗的MSP430为主控,利用DHT11芯片检测温湿度,单片机处理后的温、湿度信息由nRF24L01发送给接收端,当温湿度超出阈值或检测到婴儿啼哭时进行声光报警。经实际测试,该系统运行可靠,低功耗、低成本、高实用性,具有推广价值。
A baby sleep monitoring system based on MSP430 single chip is presented for taking care of baby better and sharing new parents＇ burden.The system includes four modules,i.e.,sound detection module,humidity detection module,sound-light alarm module and wireless transmission module,which all take the MSP430 MCU as master control.The temperature and humidity measured by DHT11 and the crying signal acquired by microphone are transmitted to receiver by nRF24L01.The practical test shows that the system has advantages,such as low-power,low-cost and high-practicality.
