PRECISE AND ACCURATE: The SF000/B 50m is an ultra-small and light laser rangefinder specifically designed for size and weight-constrained applications. Its Time-of-Flight system quickly produces precise and accurate distance and speed measurements.
Accuracy is not affected by the color or texture of the surface, nor the angle of incidence of the laser beam.
The SF000 is virtually immune to background light, wind and noise, making it an ideal sensor to detect unexpected obstacles.
Description
The SF000 can take up to 388 readings per second and the configurable features and multiple hardware interfaces make the SF000 easy to connect with different types of controllers.
Operating from a regulated 5 V DC supply, the SF000 includes two communication interfaces:
- A serial port (3.3V logic level, 5V tolerant) with a configurable baud rate to connect to a host controller.
- An I2C serial bus (3.3V logic level and 3.3k pull-up resistors, 5V tolerant) with a 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 SF000 LiDAR is rated laser Class 1M eye-safe. Do not view the laser with magnifying optics such as microscopes, binoculars, or telescopes.

- Multiple return signals, signal strength, noise measurement etc.
- Measuring range 0.2 to 50 m (80% reflective, large target)
- Incredibly lightweight; only 8.8 grams
- Adjustable measuring speed: 48 - 388 readings per second (configurable)
- Compatible with Serial and I2C and servo driver applications
- Integration: User APIs, LightWare Studio
- Sensor is eye-safe with a Class 1M rating
- No IP rating; contains open frame
- Upgradable through the LightWare Studio application
- Open frame no IP rating
They can be mounted in a downward facing orientation for altimetery, terrain following or precision landing applications. For terrain following, install the rangefinder at an angle to reduce lag time in reaction. The angle depends on the speed traveled, and the overall system lag, but should be between 20 and 45 degrees. They can be mounted forward facing orientation for sense-and-avoid or position-hold applications.
