In order to achieve real time monitoring on daily dynamic human oxygen saturation of blood

a kind of active oxygen sening tag is designed.Reflective type blood oxygen senitive probe is used

reflective noninvasive measurement principle of blood oxygen saturation and oxygen detection method are introduced

corresponding circuit is designed.nRF24LE1wireless transceiver chip is used as the core

active RFID label launch system is built

and blood oxygen detection technology are combined with RFID technology

wireless transmission of blood oxygen detection is realized

miniaturization of blood oxygen monitoring device is designed and realized

improves the wearablility and it is suitable for realtime monitoring in daily dynamic environment.
