The embodiment of the application can adopt a mode of comparing while detecting when determining the maximum light sensation signal intensity value. For example, the light sensing device initially feeds back the light sensing signal intensity value S1 read by the light sensing device at point a and the corresponding detection position to the microcontroller for storage at the point a; then the microcontroller controls the light sensing device to move to the next detection position B, and then the light sensing signal intensity value of the B point is read S2.

The optimal pulse signal detection position obtained by the above embodiment is not fixed, but can be updated as needed. For example, the update frequency of the optimal pulse signal detection position may be set in advance, such as once every half hour/every hour, or the optimal pulse signal detection position may be updated in time according to the feedback of the user. The specific updating method is to perform the detection again according to the above-mentioned procedure of determining the optimal pulse signal detection position. The embodiment of the application can improve the long-time average pulse testing accuracy and improve the user experience by updating the optimal pulse signal detection position regularly or irregularly.

Two motor driving chips can be configured in the pulse detection product to drive the two micro motors to operate. For example, the X-axis micro motor is responsible for mechanically driving the light sensing device to move along the X-axis direction, the Y-axis micro motor is responsible for mechanically driving the light sensing device to move along the Y-axis direction, and the combination of the two can realize the free movement and detection of the light sensing device in a square area with a certain area. The light sensing device feeds back the light sensing signal to the microcontroller for recording and comparison; the rear Hall sensor of the micro motor records the motion state of the motor and also feeds back signals to the microcontroller, and the microcontroller calculates and records the position of the motor. Within a set time, the microcontroller finds the best pulse signal detection position by comparing the light sensation signal intensity values of different detection positions, and drives the light sensation element to move to the best pulse signal detection position and fix through the micro motor so as to monitor the pulse signal at the position.
