Product Details
- HC-SR04 Ultrasonic Sensor：This is a device that can use sound waves to measure the distance of an object. It measures distance by emitting a sound wave of a specific frequency and listening to the bounce of that sound wave. The distance between the sonar sensor and the object can be calculated by recording the time elapsed between the generation of the sound wave and the bounce of the sound wave
- Working Voltage: 5V DC；Quiescent current: less than 2mA
- Ranging Distance：2cm - 450 cm；High precision: 0.3 cm
- Effectual Angle: <15°
- Test mode ：Test distance = ((Duration of high level)*(Sonic :340m/s))/2

Customer Questions & Answers
-
Question:
What is the HC-SR04 Ultrasonic Sensor Module used for?
Answer: The HC-SR04 Ultrasonic Sensor Module is primarily used for distance measuring. It emits ultrasonic waves and calculates the time taken for the waves to return after hitting an object, providing accurate distance readings. This functionality makes it perfect for robotics, obstacle avoidance, and automation projects, where real-time distance measurement is essential. -
Question:
Is the HC-SR04 compatible with all Arduino boards?
Answer: The HC-SR04 is compatible with various Arduino boards, including R3, MEGA, Mega2560, Duemilanove, and Nano. Its flexibility allows hobbyists and developers to integrate this sensor into a wide range of projects, from simple prototypes to complex robotic systems. Ensure to check specific pin configurations to establish the correct connections. -
Question:
How does the HC-SR04 sensor communicate with an Arduino?
Answer: The HC-SR04 communicates via digital pins on the Arduino using the Trigger and Echo pins. You send a pulse signal from the Trigger pin to start the measurement, and the Echo pin receives the returning pulse. The Arduino then calculates distance using the duration of the pulse. This straightforward communication makes it an ideal choice for beginners and experienced developers alike. -
Question:
What is the range and accuracy of the HC-SR04 Ultrasonic Sensor?
Answer: The HC-SR04 can measure distances ranging from 2cm to 400cm with an accuracy of about +/- 3mm. This range is sufficient for numerous applications such as robotic navigation and liquid level sensing. Moreover, its high accuracy makes it a reliable choice for projects that require precision in distance measurement. -
Question:
Can I use multiple HC-SR04 sensors in one project?
Answer: Yes, multiple HC-SR04 sensors can be used simultaneously in a project. However, care must be taken to ensure that they do not initiate measurements at the same time, as this could result in inaccurate readings. Utilizing separate trigger timings or introducing delays can mitigate interference, allowing for more complex setups such as multi-directional obstacle detection in robotics. -
Question:
What kind of power supply does the HC-SR04 require?
Answer: The HC-SR04 operates on a voltage between 5V to 15V, with 5V being the standard typically used with Arduino boards. It is crucial to ensure that the power supply is stable to maintain consistent performance and accuracy. This low power requirement makes it suitable for battery-operated projects, particularly in mobile robotic applications. -
Question:
How can I troubleshoot common issues with the HC-SR04?
Answer: Common issues with the HC-SR04 include incorrect wiring, inconsistent readings, and sensor failure. Verify the connections and ensure that the trigger and echo pins are properly assigned in your code. If readings appear inaccurate, check for obstructions, and consider environmental factors such as temperature, which can affect ultrasonic wave propagation. These troubleshooting steps are essential for ensuring reliable sensor performance. -
Question:
What applications can I use the HC-SR04 Ultrasonic Sensor for?
Answer: The HC-SR04 is widely used in various applications such as robotics for obstacle avoidance, proximity detection for security systems, and in smart home projects for automation. Its ability to provide accurate distance measurements makes it suitable for diverse scenarios, including parking assistance in vehicles or as part of a range-finding device in drones. -
Question:
Is any special programming required to use the HC-SR04?
Answer: Basic programming skills are required to use the HC-SR04 with Arduino. You will need to write code to trigger the sensor and read the echo signal to calculate distances. Many online resources and libraries are available that simplify the coding process, which can be useful for beginners. Leveraging these resources can make coding more approachable for those new to Arduino and sensors. -
