High‑Performance Medium‑Range Detection

This Time‑of‑Flight ranging module provides stable and accurate distance measurement across a wide detection span from 0.1m to 40m. A minimal blind zone of only 10cm enables precise measurement even at close range. The scanning frequency can reach up to 1000Hz, supporting high‑speed real‑time sensing for moving targets. Strong ambient light resistance up to 100K lux allows reliable operation in bright outdoor environments, making this industrial laser distance sensor suitable for UAV altitude control, obstacle detection, and intelligent traffic monitoring systems.

Industrial‑Grade Reliability and Protection

This solid‑state distance sensor adopts an RS485 communication interface for robust data transmission across industrial control networks. A durable PC/ABS/PMMA enclosure provides IP65 protection against dust and water ingress, supporting outdoor deployment and harsh operating conditions. Reverse polarity protection safeguards internal circuitry, while a wide input voltage range of 7–30V helps reduce system damage caused by unstable power supplies. Such electrical and mechanical durability makes this ranging device appropriate for agriculture automation, smart parking infrastructure, and transportation monitoring.

Flexible Integration with Development Platforms

This compact laser ranging unit integrates easily with embedded control platforms used in robotics and automation. Compatibility with Arduino development systems can be achieved through the Arduino UNO R3 combined with a TTL‑to‑RS485 shield. Integration with Raspberry Pi platforms is possible using a USB‑to‑RS485 module. These connection methods simplify deployment in robotics controllers, edge computing devices, and embedded sensing systems.

Pulse Time‑of‑Flight Measurement Principle

The distance sensing module operates using Pulse Time‑of‑Flight (PTOF) technology. A narrow pulsed laser beam is emitted and collimated through the transmitting lens before reflecting from the target surface. Reflected light enters the receiving optics and is focused onto an APD detector. Circuit amplification and filtering measure the time difference between transmitted and received signals. Distance is then calculated according to the speed of light, enabling accurate and repeatable ranging for industrial monitoring and robotic perception tasks.
