We will connect these four pins on the HC-SR04 ultrasonic sensor to the Arduino board via a breadboard. Setting Up an Ultrasonic Sensor for Arduino By sfrench2019 in Circuits Arduino 847 1 Download This instructable will guide you through setting up and calibrating an ultrasonic sensor for use with an Arduino system in order to accurately measure distance. GND (this will connect to GND on Arduino) ![]() TRIG (this we will connect to digital pin 12 on ArduinoĮCHO (this will connect to digital pin 11 on Arduino ![]() VCC (this will connect to 5V on the Arduino) Easily integrate the sensor in your application Collaborators Our collaborators serve as case studies to show you how the sensors are being used in an end user application. Im trying to connect five ultrasonic sensors (HC-SR04, to be exact) to an Arduino board to detect obstacles in five directions (four cardinal + one Z-axis). Discuss your application with our support team 2. Required partsįor this project, you will need the following: weather-resistant Ultrasonic Sensor to an Arduino, with code examples. Ultrasonic sensors can be used in a range of Arduino projects, for example, sensor lights (turning on a light when something or someone is in front of the sensor) and in an autonomous car (detecting and avoiding obstacles). The HC-SR04 sensor can detect obstacles between approximately 2 to 450cm range. It emits ultrasound at 40,000 Hz (40kHz) which travels through the air and bounces off obstacles in its path back to the ultrasonic sensor module. The travel time of the ultrasound is then used to calculate the distance between the ultrasonic sensor and the obstacle. An Ultrasonic Sensor is used to measure distance and can detect obstacles or nearby objects. In this lesson, you will learn how to connect an ultrasonic sensor (HC-SR04) to an Arduino.
