Description

The Broadcom? AFBR-S50LV85D is a multipixel optical

distance and motion measurement sensor module that is

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.

Due to its ambient light suppression, use in outside

environments is possible in sunlight. The sensor accurately

measures against white, black, and colored surfaces as well

as metallic and retroreflective surfaces.

The module has an integrated infrared laser light source and

an internal clock source. A single 5.0V power supply 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.

Frame rates of up to 3 kHz are supported, depending on the

microcontroller, the data streaming mode, and the number

of evaluated pixels. For frame rates of up to 100 Hz, a dual

frequency (2f) mode is used to achieve an unambiguous

range of up to 100m.
