WHEELTEC STP-23 Single Point Laser Ranging Module Serial Port Output High Precision Dynamic Ranging TOF Measurement

WHEELTEC STP-23 Single Point Laser Ranging Module Serial Port Output High Precision Dynamic Ranging TOF Measurement

Difference between STP-23 and STP-23L:
- The STL-23L module has a higher cost-effectiveness, smaller size, lower data output frequency, and can be transmitted at lower baud rates, resulting in higher single measurement accuracy; However, STP-23 has a built-in high-frequency laser ranging module of LiDAR level, which has an ultra-high sampling frequency and can take multiple data averages, resulting in better data stability. Moreover, the STP-23 module has a larger ranging range.

Features:
- The laser ranging module based on the TOF principle has higher stability and better light resistance.
- The maximum measurement distance of STP-23 is up to 13.4m.
- STP-23 has a sampling frequency of 4500Hz.
- Millimeter level measurement accuracy
- The entire system supports indoor and outdoor use, effectively avoiding strong light interference, making ranging performance more stable, and achieving high-frequency and high-precision indoor and outdoor distance measurement.
- Fully compatible with ROS1 and ROS2 systems, providing SDKs for two systems, and providing relevant technical support.
- Adopting a compact structural design, it has lower power consumption, higher cost-effectiveness, and more convenient installation.
- It uses a low-power infrared laser emitter as the emission light source and is driven by modulated pulses. The laser only completes the emission action in a very short time, which complies with FDA Class 1 human eye safety.
- Support for Windows
- Support serial port reading of raw data
- Support for ROS reading for Linux
