{"id":9575110017261,"title":"4PCS HC-SR04 Ultrasonic Distance Sensor Modules with Brackets","handle":"4pcs-hc-sr04-ultrasonic-distance-sensor-modules-with-brackets","description":"\u003ch3\u003e4PCS HC-SR04 Ultrasonic Distance Sensor Modules with Brackets\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eThe HC-SR04 ultrasonic distance sensor module is a reliable and easy-to-use\nsolution for non-contact distance measurement in robotics and automation\nprojects. Using 40 kHz ultrasonic sound waves, the module accurately measures\ndistances from 2 cm to 400 cm with typical precision up to ±3 mm. It\nintegrates both transmitter and receiver functions, making it compact and\nefficient for embedded systems. The module operates on a simple principle: a\n10 μs trigger pulse initiates measurement, after which the sensor emits\nultrasonic waves and listens for the reflected signal. The duration of the\nreturned echo pulse corresponds directly to the measured distance. Designed\nfor compatibility, the standard 4-pin interface (VCC, TRIG, ECHO, GND) allows\nseamless integration with common microcontrollers, including Arduino-\ncompatible boards. It supports both 5V and 3.3V systems (with appropriate\nlevel shifting if required). With low power consumption (approx. 15 mA) and a\nfocused beam angle of approximately 15 degrees, the HC-SR04 is suitable for\ncontinuous, real-time detection tasks. This complete kit includes mounting\nbrackets, screws, jumper wires, and a reusable storage case, making it ideal\nfor both prototyping and long-term projects. Important: This module operates\nusing ultrasonic sound waves and does not include any wireless or radio\nfrequency (RF) communication functionality.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eAccurate Non-Contact MeasurementMeasures distance from 2400 cm with typical accuracy up to 3 mm.
