For our project, we are designing a wireless monitoring pulse oximeter, blood oxygen concentration (SpO2) and fall detection system.  It consists of four units, which are  the Receiving Display unit (RDU), and three Transmitting Sensor Units (TSU).  All of the units will be worn by the patient.  The finger sensor will obtain pulse and SpO2 and transmit, the chest and thigh sensor will determine the patients posture information, and the waist display will receive data, display data, and transmit emergency signals.
