Product Description

The LRF10VB is a compact single-point LiDAR sensor based on the direct time-of-flight (DToF) principle. It is designed as a short-range distance engine for camera focusing, security monitoring, speed detection and smart devices that need fast, reliable distance information instead of long-range ranging.

The module measures from 0.05 m to 9 m on natural targets with a resolution of 1 cm. Typical accuracy is ≤5 cm within 5 m and ≤15 cm from 5–9 m, which is sufficient for autofocus, person/object detection and near-field obstacle sensing. With a measuring frequency of up to 50 Hz, the LRF10VB can track distance changes in real time, supporting responsive camera AF algorithms and high-frequency safety or counting applications.

To cope with real-world lighting, the LRF10VB provides ambient light immunity up to 70k lux, allowing stable operation in bright indoor environments or outdoor scenes with strong sunlight. The laser is classified as Class 1 eye-safe, making it suitable for products used around people, including smart home devices, security sensors and consumer equipment. The operating temperature range of −20 to +60°C and storage range of −30 to +80°C cover most indoor and light outdoor conditions.

Electrically, the sensor is powered from 4.5–5.5 V with power consumption ≤0.9 W, which is easy to supply from standard 5 V rails in embedded systems. Communication uses a UART interface (TTL level) with a default baud rate of 460800 bps, so microcontrollers and embedded Linux platforms can read distance data directly without extra interfaces. Data is transmitted as simple frames containing a fixed header, distance in centimetres and checksum, making it straightforward to parse in firmware or application software.

Mechanically, the LRF10VB is extremely small, with typical dimensions around 12 x 7.5 x 9.1mm and an optical layout optimised for single-point ranging, as shown in the optical path and spot-size diagrams. The small footprint and low weight make it easy to embed in camera modules, PTZ heads, compact security sensors, interactive terminals and industrial fixtures where board space is tight but precise distance information is still required.

Typical applications include camera focusing assistance, where the LiDAR provides absolute distance to support accurate AF in low-texture or low-contrast scenes; security monitoring and access control, where presence, approach distance or occupancy can be detected; and smart devices or light industrial equipment, where a fast 9 m LiDAR channel is needed for position sensing, object detection or speed and distance measurement.
