Vishay VCNL4035X01 Proximity and Ambient Light Sensor combines photo detectors for proximity and ambient light, a signal conditioning IC, a 16-bit ADC, and a driver for up to three external IREDs in one compact 4mm x 2.36mm x 0.75mm surface-mount package. The AEC-Q101 qualified sensor features an interrupt function and supports I2C bus communication interface for portable electronics and smart home, industrial, and automotive applications.
The VCNL4035X01 Sensor can be implemented to provide gesture recognition in consumer electronics such as notebooks and tablets; presence detection for display activation in printers, copiers, and automobiles; collision avoidance in toys and robots; and lighting control in offices, corridors, and public buildings. All the circuitry needed for these applications is included in one compact device to save PCB space, while its utilization of external emitters for gesture applications provides greater design flexibility.
