Broadcom AFBR-S50MX85I Time of Flight

AFBR-S50MX85I is a multipixel optical distance and motion measurement sensor module based on the optical Time of Flight principle. The technology has been developed with a special focus on applications that need the highest speed and accuracy at medium distance ranges, with a small size and very low power consumption. The sensor accurately measures against white, black, coloured, and metallic and retroreflective surfaces. The module has an integrated infrared laser light source and an internal clock source. A single power supply of 5.0V is required. Data is transferred using a digital serial peripheral interface (SPI) using standard 3.3V CMOS levels. For system health monitoring, a reference pixel is used in addition to the integrated voltage and temperature sensors. Applications include obstacle and void detection, human-machine interfaces, robotics, automation and control, security surveillance, inventory monitoring, and augmented reality.
