Range limitations
Doesn't detect objects closer than 25cm which was a bit inconvenient for my specific application.

Great for robotics
Works perfectly with my Arduino Uno. The waterproofing is solid and it reads distances consistently.

Good but cable stiff
Sensor is accurate but cable is hard to route in tight spaces. Otherwise functions as expected.
5 FAQ
Q: What is the maximum voltage tolerance?
A: Do not exceed 5.5V to prevent permanent damage to the circuitry.
Q: Does this output analog or digital data?
A: It outputs serial data corresponding to the measured distance via the TTL interface.
Q: Is a library available for Arduino?
A: Yes, standard ultrasonic libraries often work with adjustments, or you can use the serial example provided in our docs.
Q: Do you offer bulk pricing for schools?
A: Please contact our sales department directly for orders exceeding 50 units for educational discounts.
Q: Can I cut the cable to make it shorter?
A: We do not recommend cutting the cable as it will void the waterproof sealing and may damage the module.
