SF22/C LiDAR sensor
Datasheet
1. Overview
The SF22/C is a LiDAR API development kit that can be used to test out new applications before investing in more expensive
devices. It is a small form factor, general purpose LiDAR sensor that measures the distance to objects by timing a laser flash.
Accuracy is not generally affected by the colour or texture of the target surface, nor the angle of incidence of the laser beam.
The SF22/C is tolerant to changes in background lighting conditions, wind and noise.
The following capabilities are included in the SF22/C as standard:
● Measurement to the nearest detected surface (first return).
● Measurement to the farthest detected surface (last return).
● Selectable filters to adjust the dynamic response to moving targets.
● Adjustable measuring update rate.
● Internal status monitoring.
There are three communication interfaces available:
● A micro USB port that connects to a PC running the !LightWare Studio application for visualisation of results, to
make configuration changes and for upgrading the firmware.
● A serial port (3.3V logic level) with configurable baud rate to connect to a host controller.
● An I2C serial bus (3.3V logic level and 3.3k pull up resistors) with configurable address as an alternative to the serial
port when multiple devices are connected on a common bus.
Application software support is available from the LightWare !API! repository.
The SF22/C LiDAR API development kit is rated laser Class 1M eye safe. Do not view the laser with magnifying optics such as
microscopes, binoculars or telescopes.
