Home Environment Monitoring System Based On Internet Of Things

Family life is an indispensable part of human daily life.The rapid development of modern urbanization and industrialization and the relatively lack of environmental protection measures have made people's awareness of safety stronger and stronger,the quality of family environment has also become a criterion for measuring healthy life.Although the indoor environment changes slightly,it directly affects a person's health level.Long-term living environment with low doses of harmful substances will also bring hidden dangers to human health.In order to grasp the changes of family environment information in real time and eliminate the potential safety hazards in family environment,this paper designs a family environment monitoring system based on the Internet of Things.According to Proteus visual program,the software simulation circuit of acquisition signal is designed,and the hardware integration circuit for designing multiple sensor signals using Arduino,the signal is transmitted to iTop-4412 development board based on minimal Linux system by TX serial port.After iTop-4412 development board serial port driver settings,the signal is read by GPIO serial port.Finally,the read signal is divided into two parts to display the family environment signal.One part transmits the information to the computer through ZigBee module to realize the remote communication of data.The other part displays the home environment information on the Web page through the Boa server built in iTop-4412 development board,and displays the home environment information online and real-time in the form of landing users.In the aspect of system performance validation,the environmental signals which are collected by Arduino are analyzed,and a set of usage standards are worked out according to the actual signal errors in the laboratory environment,which makes the home environment monitoring system of the Internet of Things more perfect.
