An designing of oxygen saturation detection module based on ZigBee technology

In this paper, the technology of ZigBee based on wireless sensor network was adopted to carry out the real-time oxyhemoglobin saturation monitoring. C8051F340 was used to control UZ2400 as MCU(Micro Control Unit). Electricity was consumed less than 2mA when it worked and electricity was consumed less than 1µA when it slept. This system can prolong the life time of battery effectively. And the system avoided tedious A/D conversion which the traditional sensor needs and its measure precision is good.
