May 2, 2024 · Learn how to use the ultrasonic sensor (HC-SR04) with Arduino. This tutorial will teach you what it is, how to assemble the sensor on Arduino, and, at the end, you'll implement it into an alarm system project.

HC-SR04 Ultrasonic Module Timing Diagram We need to transmit trigger pulse of at least 10 us to the HC-SR04 Trig Pin. Then the HC-SR04 automatically sends Eight 40 kHz sound wave and wait for rising edge output at Echo pin.

Oct 7, 2021 · We provide a schematic diagram on how to wire the ultrasonic sensor and an example sketch with the Arduino. The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object. This sensor reads from 2cm to 400cm (0.8inch to 157inch) with an accuracy of 0.3cm (0.1inches), which is good for most hobbyist projects.

You can use the following table as a reference or take a look at the schematic diagram. DS3231 RTC Module: ... Arduino Reed Switch. Arduino Ultrasonic Sensor. Arduino SD ...

Ultrasonic sensor HC-SR04 is used to measure the distance to an object by using ultrasonic waves. The ultrasonic sensor HC-SR04 includes four pins: TRIG pin: this pin receives the control signal (pulse) from Arduino. ECHO pin: this pin sends a signal (pulse) to Arduino. Arduino measures the duration of pulse to calculate distance.

Sep 20, 2019 · Ultrasonic Sensors measure the distance to the target by measuring the time between the emission and reception. The following shows a breadboard component diagram which will be used for this project.
