The blood oxygen detection mainly comprises the following components: integrated chip, dual wavelength infrared transmitting tube, infrared receiving tube.
The function is achieved by monitoring the ratio of oxygen-carrying hemoglobin to non-oxygen-carrying hemoglobin in the artery and can display the user's pulse (heart rate). Because hemoglobin in human blood has an absorption effect on infrared light, the amount of blood circulating in a part to be detected of a human body is increased at the instant of heart pulsation of a detected person, and the total amount of infrared light absorbed by the hemoglobin is relatively large; when the amount of blood flowing through the part to be measured of the human body is reduced in the heart beat gap of the examiner, the hemoglobin absorbs the total amount of infrared light, and therefore the amount of infrared light absorbed by the part to be measured of the human body is detected by the infrared light sensor.

The size is 6.0 × 4.8 × 1.1mm, the emission wavelength is 660/905nm, and the detection requirement of the blood oxygen module is met.
The infrared receiving tube selects PD60-48C/TR8, and is matched with an IRR60-48C/TR8 infrared transmitting tube for use, the reaction speed is high, the sensitivity is high, the operation is high, and the size is 6.0 x 4.8 x 1.1 mm.
Blood sugar test mainly comprises the following components: red light emitting tube, red light receiving tube.
The Raman spectrum technology is adopted for detection, the tissue is irradiated by visible light and near infrared light, and a scattering spectrum with different incident light frequency is obtained, so that analysis is carried out to obtain information on molecular vibration and rotation. The blood sugar index data can be preliminarily calculated by detecting the ratio of the transmission energy of the part to be detected of the user to visible light and infrared light, and then the parameters of the blood oxygen module and the temperature module are led in for correction, so that noninvasive blood sugar detection data with higher precision can be obtained. Specifically, the change in the blood glucose level is visually reflected as a change in the absorption energy (or transmission energy) of human blood with respect to visible light and infrared light.
