The present invention discloses an elastic photoelectric sensor module, which is mainly used for monitoring of physiological parameters such as human heart rate, blood oxygen saturation and a blood pressure based on optical inspection. The module includes a sensor structural part (1), an elastic telescopic unit (2), a sensor window group (3), and a photoelectric sensor (4). The sensor structural part (1) provides structural support for the sensor device, and the elastic telescopic unit (2) provides elastic force for the device. The sensor window group (3) is a signal path, and the photoelectric sensor (4) is a basic signal detection unit.
