A physiology measuring device and system are disclosed. The device includes two light-emitting units and a detecting unit. Each one of the two light-emitting units provides a light projecting to respective one of two positions of a limb. The detecting unit receives the reflected lights from the projected positions of the limb and transfers the received lights out as measuring signals.一種生理量測裝置及系統。生理量測裝置包含二個發光單元及檢測單元。前述的二個發光單元分別提供輻射光照射至一身體部位的二個受測位置,再個別被前述身體部位的二個受測位置反射。檢測單元分別接收上述的反射光並轉換輸出為感測訊號。100‧‧‧生理量測裝置130‧‧‧第一發光單元131‧‧‧第一輻射光133‧‧‧第一反射光150‧‧‧第二發光單元151‧‧‧第二輻射光153‧‧‧第二反射光170‧‧‧檢測單元L‧‧‧肢體部位P1‧‧‧第一受測位置P2‧‧‧第二受測位置
