HKIG-07B infrared pulse sensor The product is a fingertip using infrared light transmission parts, the output response of peripheral vascular changes in blood volume pulse sensor. Output voltage in the form of an analog signal. The internal sensor includes amplification and filtering circuits. User-friendly and can be widely used in a variety of pulse wave acquisition system. Because the ambient temperature has a greater impact on human blood flow, winter and summer vary greatly, so the output amplitude of the sensor also varies with changes in temperature differences, the output amplitude peaks in winter 0.1-0.3V, summer 0.6-1.5 V? supply voltage 5VDC? current of about 15mA? optoelectronic receiver sensitivity 0.62A / W
