Perfect for Arduino Robotics
Works exactly as expected. Easy to wire and plenty of libraries available. Measured distances accurately in my obstacle avoidance robot.

Best value ultrasonic sensor
Can't beat the price for this quality. Used it for a parking sensor project and it was responsive enough.

Good sensor, mind the voltage
Great module overall. Just be careful if connecting to 3.3V logic boards without a level shifter. Otherwise, solid performance.

One defective unit
Ordered a pack of two. One worked great, the other didn't echo any signal. Seller replaced it quickly though.

Reliable Distance Measurement
I bought five of these for a project. All of them worked out of the box. Consistent readings within the specified range.
Q: Can this be used outdoors?
A: It can be used outdoors, but wind and temperature may affect the speed of sound and readings.
Q: How many pins does this module have?
A: It has 4 pins: VCC, Trigger, Echo, and GND.
Q: What is the accuracy of this sensor?
A: Typically within 3mm under ideal conditions, but surface material affects accuracy.
Q: Is there a library available for Arduino?
A: Yes, there are many open-source libraries available on the Arduino Library Manager.
Q: Can I use this with a 3.3V microcontroller?
A: Yes, but we recommend using a voltage divider or level shifter for the Echo pin to protect your board.
