ANGEEK 5PCS HC-SR04 to World Ultrasonic Wave Detector Ranging Module for arduino Distance Sensor

The VL53L0 uses ST's FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector, so it can be considered a tiny, self-contained lidar system..
ST's VL53L0 module is simple and easy to use (6 valid pins), provides an I2C interface, is equipped with a full set of API drivers and technical documents, making system integration fast and simple. The module package supports the reflow soldering process, complies with the RoHS hazardous substance restriction standards, and is fully compatible with various glass covers and appearance designs..
Unlike traditional infrared proximity sensors, the color and reflected light of the target object will not affect the distance measurement results. But its effective range and accuracy largely depend on environmental conditions and target characteristics, such as reflectivity and size, and sensor configuration. (The accuracy of the sensor is specified as ±3% at the highest, and it is over ±10% under the next best conditions.).
The internal laser emits non-visible light with a wavelength of 940nm, which does not harm the eyes, eliminates the problem of distracting people from emitting red light with other infrared....
