Works as expected
Good sensor but needs 5V logic level for echo. Had to use a voltage divider for my ESP32.

5 FAQ
Q: What is the resolution of the measurement?
A: The resolution can reach up to 3mm under ideal conditions.
Q: Is this module waterproof?
A: No, this module is not waterproof and should be kept dry.
Q: What is the maximum effective range?
A: The maximum effective measuring range is 400cm.
Q: Does the package include jumper wires?
A: No, jumper wires are not included in the package.
Q: Can I use this with 3.3V microcontrollers?
A: Power supply must be 5V. The Echo pin outputs 5V, so use a voltage divider for 3.3V MCU input.
