The SparkFun Ultrasonic Distance Sensor - TCT40 (sen-24805) a user-friendly upgrade to the popular HC-SR04 sensor, offers non-contact distance measurement from 2cm to 400cm with an accuracy of 3mm.

This is a library for the Arduino IDE that helps interface with ST's VL53L4CD time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

Abstract: Proximity sensing is of great importance for robot control during human–robot collaboration (HRC). Commonly used machine vision sensors or photodetectors are subjected to the light block ...
