This paper introduces the design of traditional photoelectric pulse sensor, researches the measure noise and realizes the improvement of the sensor. Laser diode is used instead of traditional LED to improve the quality of the light source. The circuit is designed based on double OPT101,and the signal detection circuit is improved. Data communication is proposed based on nRF24E1 and data wireless communication is realized. The test results indicate that the system can efficiently remove the system noise and improve the precision of measure.
