EVERLIGHT ALS-PD50-42C sensor for wearable applications

Mining green 550nm band, the photosensitive area 8.1mm2, the output current efficiency is high, the heart rate calculation of the most real-time accurate
Xintai Electronics Industry Co., Ltd. [TSE: 2393] introduced the new ALS-PD50-42C series of ambient light sensor, mining green light of the 550nm band , The signal calculation error is low, the output current efficiency is high, easy to detect heart rate signal, especially for sports watches and other wearable applications.
In recent years, the impact of the concept of health, the national movement of prosperity, but also on the health management and sports performance more attention, with the evolution of technology, today's sensor can be described as the most intelligent way to non-invasive light volume principle PPG ( Photoplethysmogram), through the launch of the green LED reflected to the sensor after the sensor output current changes, induction of blood vessels in the blood flow changes, and calculate the heart rate signal. Evergreen ALS-PD50-42C series for the most advanced environmental light sensor, mining large area of the design area, the photosensitive area of 8.1mm2, the main consideration of the subject's skin contact, vulnerable to color, tattoos or hair interference, Area can increase the ability to identify the signal to receive more strongly and stable, and even to move or runners, can be the most real-time, easily detected heart rate.
ALS-PD50-42C series of products in the 100Lux white LED irradiation, there is 0.8 μA current signal output (Vr = 5V), so excellent photoelectric conversion efficiency, better analysis of skin surface microvascular reflected light energy signal, plus On the special coating design, effectively reduce the 400nm below the ultraviolet light and 650nm above the infrared light interference, reduce the outdoor movement of the impact of excessive sunlight, the detection results are more accurate. ALS-PD50-42C series withstand temperature -40 ° C to 85 ° C, can be used at 0 to 5V voltage, while RoHS, lead-free and halogen-free specifications, very suitable for sports wear and other wear-oriented applications to The most portable way to capture heart rate information.
Billion light with professional R & D, business and marketing team, with more than 33 years of professional development capabilities in the packaging technology continue to pursue innovation and breakthroughs to provide customers with a variety of impeccable product solutions.
Samples and technical support: available now on demand
Mass production: the third quarter of 2016
