Works but needs logic level shifting
Just a heads up for 3.3V users, you might need a level shifter. Works fine on 5V though. Documentation mentions it but easy to miss.

Reliable Distance Measurement
Tested against a tape measure and it is surprisingly accurate within the 2-400cm range. Great value for the price.

Good sensor, minor wiring confusion
The sensor itself is great. Took me a bit to figure out the 5th pin function compared to the standard 4-pin HC-SR04. Otherwise solid.

Perfect for Arduino Robotics
Works flawlessly with my Arduino Uno. The range is accurate enough for obstacle avoidance. Documentation helped me get started quickly.

Excellent Documentation Included
Unlike other modules, this came with a clear pinout sheet. Saved me time searching online. Highly recommend for beginners.
Q: What is the difference between this and HC-SR04?
A: The HY-SRF05 has 5 pins including a dedicated OUT pin, offering slightly different interface options compared to the standard 4-pin HC-SR04.
Q: Is this compatible with Raspberry Pi GPIO?
A: Yes, but ensure you use a voltage divider for the echo pin as Pi GPIO is 3.3V tolerant.
Q: Can this be used outdoors?
A: It can function outdoors, but wind and temperature variations may affect accuracy. Best used in controlled environments.
Q: Does it come with sample code?
A: The documentation includes basic Arduino example code to get you started with distance calculations.
Q: What is the minimum detection distance?
A: The minimum measurable distance is approximately 2cm. Objects closer may not be detected accurately.
