Good value
Works well but sensitive to soft surfaces that absorb sound. Good price though.
Q: Does this work with 3.3V logic?
A: It requires 5V power, but echo output is 5V. Use a voltage divider for 3.3V MCUs.
Q: Can I use this underwater?
A: No, this sensor is not waterproof and uses air ultrasonic waves.
Q: How many pins does it have?
A: It has 4 pins: VCC, Trigger, Echo, and Ground.
Q: Is code example included?
A: No, but many libraries exist for Arduino and STM32 online.
Q: What is the minimum distance?
A: The minimum measurable distance is approximately 2cm.
