Aimed at the defects of traditional monitoring system
a real-time indoor environment monitoring and warning system based on wireless sensor networks is designed.And the architecture of the system is given.The system uses CC2430 as the core of the wireless sensor networks
indoor CO volume fraction
smoke volume fraction and temperature are collected and monitored real-time.ARM microprocessor S3C44B0X is used as the central control component
which stores
analyzes and deals with the environmental information collected.And the SIM300 module is used for transmitting data remotely.When a fire or a gas leakage occurs
users receive alarm information by mobile phone in a timely manner.Experiments show that the system is simple
economical
stable.It can accurately forecast the indoor fire and gas leakage.
