A photoelectric heart rate detection system includes an array detection module, a blood vessel scanning positioning module and a heart rate monitoring module. The array detection module includes a plurality of photodetection units arranged in a two-dimensional array, each photodetection unit having a μLED and a CIGS optoelectronic component. The blood vessel scanning positioning module can drive the photoelectric detecting units to operate sequentially, and locate the blood vessels according to the array address of the photoelectric detecting units and the sensing signals outputted. The heart rate monitoring module analyzes the sensing signals of the photodetecting units aligned with the blood vessels to obtain heart rate data. Through the two-dimensional array setting design of the photoelectric detecting unit, the present invention can first locate the blood vessel position of the limb to be tested, and then position and control the photoelectric detecting unit of the aligned blood vessel to perform heart rate monitoring, which can be measured. More accurate heart rate data.一種光電式心率偵測系統，包含陣列偵測模組、血管掃描定位模組及心率監測模組。陣列偵測模組包括多個以二維陣列設置的光電偵測單元，每一光電偵測單元具有一μLED及一CIGS光電元件。血管掃描定位模組能驅動該等光電偵測單元依序作動，並根據該等光電偵測單元之陣列位址與輸出之感測訊號而定位出血管。心率監測模組會分析對準血管的光電偵測單元的感測訊號而得到心率資料。透過該等光電偵測單元的二維陣列設置設計，使本發明能先定位出待測肢體的血管位置後，再定址控制對準血管的光電偵測單元作動以進行心率之監測，能測得更準確的心率資料。
