Great for Robotics
Used this for my obstacle avoidance robot and it works flawlessly. The range is accurate enough for indoor navigation.

Reliable Component
Bought ten units for a class project. All were working perfectly out of the box. Consistent performance across all modules.

Good Accuracy
Works well within the specified range. Sometimes struggles with soft surfaces but overall a solid sensor for the price.

Solid Value
Good price for the performance provided. Shipping was fast and packaging protected the pins well.
Q: Can I use this sensor underwater?
A: No, this is not waterproof and ultrasonic waves do not propagate well from air to water.
Q: Is a code example included in the package?
A: Physical code is not included, but links to datasheets and example libraries are provided in the product description.
Q: Does it work with 3.3V logic levels?
A: It is designed for 5V systems. For 3.3V microcontrollers, a voltage divider is recommended for the Echo pin.
Q: What is the resolution of the measurement?
A: The resolution is up to 3mm depending on the environment and surface material.
Q: How does surface material affect accuracy?
A: Accuracy varies with surface. Hard, flat surfaces reflect best. Soft or angled surfaces may reduce range.
