ENERGY-CRITICAL: The SF23/B is a low-power LiDAR that can be used in energy-critical applications where batteries or solar cells are used. The SF23/B is tolerant to changes in background lighting conditions, wind, and noise.
Overview
The SF23/B is a low-power LiDAR that can be used in energy-critical applications where batteries or solar cells are used. 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 color or texture of the target surface, nor the angle of incidence of the laser beam.
The SF23/B is tolerant to changes in background lighting conditions, wind, and noise.
Uses
- Adjustable measuring update rate.
- Internal status monitoring.
- Measurement to the nearest detected surface (first return).
Communication interfaces include:
- A serial port (3.0V logic level) to connect to a host controller.
- A shutdown control line.
- A general-purpose control line.
Application software support is available from the LightWare API repository.
Dimensions
Installation
SF23/B requires a clear line-of-sight to measure distance to a target surface. It can be mounted with a vertical or horizontal lens orientation.
The SF23/B LiDAR is rated laser Class 1 eye-safe. Do not view the laser with magnifying optics such as microscopes, binoculars, or telescopes.
- Measures up to 50m in outdoor conditions
- Will operate from a small solar panel or coin cell battery
- Can take from 1 to 10 readings per second
- Battery, solar or energy critical applications
- 32 mm x 30 mm x 22 mm
- 10 grams
- 0.1 to 20 readings per second (configurable)
- Eye safe laser emission Class 1
- Open frame, no IP rating
- User APIs, LightWare Studio
The SF23/B emits ionizing laser radiation. The level of the laser emission is Class 1 which indicates that the laser beam is safe to look at with the unaided eye but must not be viewed using binoculars or other optical devices. Notwithstanding the safety rating, avoid looking into the beam and switch the unit off when working in the area.
Caution : The use of optical instruments with this product will increase eye hazard.
The SF23/B should not be disassembled or modified in any way. The laser eye safety rating depends on the mechanical integrity of the optics and electronics so if these are damaged do not continue using the SF23/B. There are no user serviceable parts and maintenance or repair must only be carried out by the manufacturer or a qualified service agent.
No regular maintenance is required for the SF23/B but if the lenses start to collect dust then they may be wiped with suitable lens cleaning materials.
