TFS20-L Capteur LiDAR à distance unique ToF – 20 m pour Arduino – DFRobot

Introduction

The TFS20-L is a fully integrated single-channel dToF ranging compact module, incorporating a high-sensitivity infrared-enhanced SPAD sensor, with a measurement range of up to 20 meters. Utilizing an all-in-one SPAD chip solution, histogram statistics algorithms, and a fast TDC architecture, it achieves high-precision ranging while offering 15m@100 Klux sunlight resistance and reflectivity correction functionality.

Compact Size, High Performance
With its small dimensions, lightweight design, and exceptional accuracy and range, the TFS20-L delivers outstanding performance even under strong ambient light, making it an ideal choice for miniaturized dToF applications.

Rich Features, Broad Applications
The TFS20-L integrates a power module, operates on a 3.3V single power supply, and features built-in temperature compensation. It supports I2C and UART interfaces for easy integration and use, along with a compact and reliable optical package. Suitable for UAV altitude hold, UAV-assisted landing, robot anti-drop, and smart device triggering.
