Ambient light sensors combine leading-edge technology with smart features

Available from Digi-Key, Maxim Integrated’s ambient light sensor measures the amount of visible light in the environment. Their sensors combine the industry's leading-edge technology with smart features for reliable and precise ambient light measurement. By integrating a superior sensor component with precise analog circuitry and digital control, their light sensors achieve high performance with an ultra-low supply current. Their proximity sensor technology measures infrared light reflected from an object. The technology is based on an innovative LED-pulsing scheme that provides reliable sensing even in extreme sunlight conditions. Low duty-cycle LED pulsing, along with integrated power control, requires drastically less sensor power, making these products perfect for handheld, battery-powered applications. Optical sensors for body wearable applications are primarily used to track physical activity, health, and wellness. Their fully integrated sensors enable continuous heart rate detection and oxygen saturation measurements in comfortable, wearable form factors. These body-wearable optical sensors combine a photo sensor, LEDs, ambient light cancellation circuitry, and a high performance analog front end to simplify design and help reduce motion artifacts. Ultra-low power consumption and leading-edge packaging technology extend battery life, reduce device size, and accelerate time-to-market.
