Real-time detection of respiration is very important for people with respiratory dysfunction. The respiration detection system based on nanomaterial humidity sensor and Zig Bee wireless network technology is designed. This system consists of four parts( that is

humidity sensor probe

data collection node

data receiver node

respiration detection software developed by MFC platform based on VC + +. This system achieves functions of record of respiratory frequency

apnea alarm

real-time display of respiratory signal waveform

etc. The effectiveness of system has been verified through experiments with several volunteers. Respiration detection system has advantages of fast response and recovery

shortness of breath can be detected

little outside interference

wireless detection

high portability

etc.
