Good value, slight noise at max range
For the price, you can't beat it. It performs well for general distance measurement. I noticed a bit of jitter when measuring objects near the 400cm limit, but for anything under 3 meters, it is very stable.

Perfect for Arduino robotics projects
This sensor works flawlessly with my Arduino Uno. The range is accurate up to about 3 meters in my testing, which is perfect for my obstacle avoidance robot. Setup was easy using standard libraries.

Bulk order quality check passed
Ordered 20 units for our club workshop. Every single module worked out of the box. The build quality feels solid, and the pins are well-soldered. Will definitely order again.

Reliable and durable
I've been using this module in an outdoor parking sensor prototype for two weeks. Despite some dust and temperature changes, it keeps giving consistent readings. Highly recommended for prototyping.

Easy to use but needs calibration
As a beginner, I found the wiring straightforward. However, I had to tweak the speed of sound constant in my code to match my room temperature for better accuracy. Once calibrated, it works great.

Great for university projects
Bought five of these for our final year project. All units arrived in good condition and performed consistently. The documentation provided by the seller helped us get started quickly.
Q: Can this sensor work directly with 3.3V logic boards like the ESP32?
A: Yes, the module supports a wide voltage range. While VCC should be 5V for optimal performance, the echo output is generally compatible with 3.3V logic inputs. However, using a voltage divider on the Echo pin is recommended for strict 3.3V systems.
Q: How do I connect this to a Raspberry Pi?
A: Connect VCC to Pin 2 (5V), GND to Pin 6 (GND), Trig to a GPIO pin (e.g., GPIO 23), and Echo to another GPIO pin (e.g., GPIO 24). Remember to use a resistor divider for the Echo pin to protect the Pi's 3.3V GPIO.
Q: Does this come with jumper wires?
A: No, the package includes only the HC-SR04 module itself. Jumper wires are sold separately, but any standard male-to-male jumper wires will work perfectly.
Q: Is it waterproof for outdoor use?
A: No, this module is not waterproof. It is designed for indoor use or protected outdoor environments. If you need it for rain-exposed applications, please consider purchasing a waterproof ultrasonic sensor variant.
Q: What is the minimum detection distance?
A: The minimum measurable distance is approximately 2cm. Objects closer than this may not be detected accurately or may return a zero value.
