The LPB40B is a single-point ranging LiDAR sensor based on Direct Time-of-Flight (DToF) technology. It measures distances from 0.05 to 40 m on high-reflectivity targets, with ±5 cm accuracy across the full range. The DToF principle allows stable operation under strong outdoor lighting up to 100 klux, and the adjustable measurement frequency (1–2000 Hz) makes it suitable for high-speed applications.
The sensor features an IP65-rated enclosure with a coated crown glass lens for durability in industrial environments. Built-in protection against reverse connection, overvoltage, and current limitation ensures reliable operation. UART output makes it easy to integrate with Arduino, Raspberry Pi, or other microcontroller platforms.

Jargon buster
Plain-language definitions for the technical terms used above.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- LiDAR
- A sensing method that uses laser light to measure distance and build a 3D picture of the surroundings. It matters for robotics and autonomous systems because LiDAR data can help with mapping, navigation and obstacle detection.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
