Reliable distance check
Consistent readings within indoor environments. Outdoor wind affects it slightly, but that is expected for ultrasonic technology.

Great for learning electronics
Used this for my university prototype. Easy to wire and understand the timing pulses. Delivery was fast too.

Bulk buy success
Bought 10 units for our club workshop. All arrived working and calibrated well. Consistent performance across all modules.

Good value for money
Solid sensor for the price. Note that it struggles slightly with soft surfaces like cloth, but works great on hard walls.

Perfect for Arduino projects
Works flawlessly with the standard NewPing library. Accurate enough for my obstacle avoidance robot car. Wiring was straightforward.
Q: Is there a library available for ESP32?
A: Yes, most Arduino ultrasonic libraries are compatible with ESP32 boards using the Arduino IDE.
Q: Can I use this with 3.3V logic boards?
A: Yes, but a voltage divider is recommended for the Echo pin to protect 3.3V boards from the 5V output signal.
Q: What is the accuracy of the measurement?
A: Typically within 3mm under ideal conditions. Accuracy may vary based on surface texture and environmental factors.
Q: Does this module come with jumper wires?
A: No, this module is sold separately. Please purchase dupont wires separately if you need connection cables.
Q: Can I use multiple sensors together?
A: Yes, but you must trigger them sequentially to avoid cross-talk interference between the ultrasonic waves.
