ANGEEK 5PCS HC-SR04 to World Ultrasonic Wave Detector Ranging Module for arduino Distance Sensor
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 proximity sensors, and enhances the anti-interference performance of external light sources. The sensor's digital architecture and automatic compensation function make it still have a high performance in scenes with high ambient light intensity..
The sensing capability of VL53L0X can support various functions, including gesture sensing or proximity of various innovative user interfaces.
wall detection, cliff detection, and collision detection of household appliances such as sweeping robots.
bathroom products, such as faucets, soap dispensers, and Cell phones and flushers.
other target applications include laptop user prese....
