How to use a ToF laser ranging sensor with Arduino and Wisblock

Laser ranging has many applications in production and life, such as ranging, positioning, obstacle avoidance, and so on. Time-of-Flight (ToF) ranging, as a type of laser ranging technology, is often used for real-time object detection in robots, autonomous vehicles, and traffic management because of its accuracy, fast response, and low power consumption. The face detection function of mobile phones also uses this technology. This article will introduce the WisBlock RAK12014 ToF laser ranging sensor module, and use the WisBlock development board to demonstrate how the module works. What is a ToF laser ranging sensor module? A ToF laser ranging sensor module uses laser pulses to measure the distance between itself and a target object. The WisBlock RAK12014 ToF laser ranging sensor module is based on STMicro VL53L0X, the smallest ToF ranging sensor in the world. The WisBlock RAK12014 provides accurate distance measurement and can measure distances up to 2 meters. […]
