Customer Questions & Answers
-
Question:
What is the HC-SR04 Ultrasonic Sensor Module?
Answer: The HC-SR04 Ultrasonic Sensor Module is a versatile component that uses ultrasonic waves to measure distances, making it ideal for various applications in robotics, automation, and DIY projects. It operates by sending out an ultrasonic pulse, which reflects off nearby objects and returns to the sensor, allowing it to calculate the distance based on the time taken for the echo to return. This module is widely used in obstacle detection, drone altitude measurement, and even in smart home devices. -
Question:
What is included in the 3PCS HC-SR04 package?
Answer: The 3PCS HC-SR04 package includes three individually packaged HC-SR04 Ultrasonic Sensor Modules, each accompanied by a set of mounting brackets and cables. This means you can easily set up multiple sensors in different locations or projects without needing to purchase additional components. The included mounting brackets allow for straightforward installation, making it convenient for both professional applications and hobbyist use. -
Question:
How accurate is the HC-SR04 Ultrasonic Sensor?
Answer: The HC-SR04 Ultrasonic Sensor typically provides reliable distance measurements within a range of 2 cm to 400 cm with an accuracy of around ±3 cm. This level of precision makes it suitable for most applications, whether you're creating a simple distance measuring device or implementing it in more complex robotics projects. For best results, ensure the sensor is level and that there are no obstacles interfering with its ultrasonic waves. -
Question:
Can the HC-SR04 be used outdoors?
Answer: Yes, the HC-SR04 Ultrasonic Sensor can be used outdoors, but with certain precautions. While the sensor is effective for measuring distances, environmental factors like wind and rain can affect its performance. When using it outdoors, ensure that it is protected from direct contact with water and that it is properly calibrated to account for any variations caused by temperature and humidity. It's ideal for applications like automated gardening systems or outdoor obstacle detection. -
Question:
What microcontrollers are compatible with the HC-SR04?
Answer: The HC-SR04 Ultrasonic Sensor is compatible with a variety of microcontrollers including Arduino, Raspberry Pi, and ESP8266. This broad compatibility allows makers and developers to integrate the sensor into their projects easily, leveraging libraries and examples available for each platform. Whether you're programming a distance measuring device or incorporating it into a larger smart system, the HC-SR04 can be paired effectively with your chosen microcontroller. -
Question:
What are some common applications for the HC-SR04 Ultrasonic Sensor?
Answer: The HC-SR04 Ultrasonic Sensor is versatile and can be used in numerous applications such as robotic obstacle avoidance, distance measurement in drones, proximity sensors in automation systems, and even in measuring liquid levels in tanks. These practical uses demonstrate the sensor's flexibility in both educational and professional settings, making it a favorite among DIY enthusiasts and engineers alike. -
Question:
How do I connect the HC-SR04 to my microcontroller?
Answer: Connecting the HC-SR04 to your microcontroller is straightforward. Typically, you'll connect the VCC pin to a 5V power source, the Trig pin to a digital output pin, the Echo pin to a digital input pin, and the GND pin to the ground. Using libraries specific to your microcontroller, you can easily send a pulse to the Trig pin and read the echo on the Echo pin to calculate distance. This setup is a crucial first step in developing distance-based applications. -
Question:
What kind of power supply does the HC-SR04 require?
Answer: The HC-SR04 Ultrasonic Sensor operates on a power supply of 5V DC. It's essential to provide the correct voltage to ensure accurate distance measurements and prevent damage to the sensor. Most microcontrollers like Arduino can efficiently supply this voltage directly, making it convenient for hobbyist projects. Always verify the power requirements and avoid exceeding the specified limits to maintain optimal performance. -
Question:
Can I use multiple HC-SR04 sensors together?
Answer: Yes, you can using multiple HC-SR04 sensors in the same project. However, it’s crucial to manage their operation to prevent interference between them. This can be done by ensuring that only one sensor emits an ultrasonic pulse at a time, allowing the others to remain silent until it’s their turn. Utilizing multiplexers or coordinating signals in your code helps achieve accurate measurements even when several modules are involved in a project. -
Question:
Where can I buy 3PCS HC-SR04 Ultrasonic Sensor Module in UAE?

“I had an excellent experience with Ubuy UAE. I ordered a product from the USA, and the website clearly mentioned that deliveries might be delayed due to the current situation in the Middle East. Despite that, my order arrived in just one week, which exceeded my expectations. The shipment was handled by DHL, and the entire delivery process was smooth, fast, and hassle-free. The package arrived in perfect condition with no issues at all. What impressed me the most was the pricing. The product was significantly cheaper than ordering the same item directly through Amazon USA and shipping it to the UAE, where I would have had to pay higher delivery charges and additional customs fees. Ubuy provided great value, transparent communication, and reliable delivery. Based on my experience, I would definitely use them again and highly recommend them to anyone in the UAE looking to purchase products from overseas. Thank you, Ubuy UAE, for a fantastic shopping experience!”
