Great upgrade from standard SR04
The wide voltage range makes this perfect for both 3.3V and 5V microcontrollers. I2C support saves GPIO pins.

Perfect for ESP32 projects
Finally a sensor that works directly with 3.3V logic without level shifters. UART mode is very stable.

Reliable distance sensing
Used this for my obstacle avoidance robot. Accuracy is consistent within the specified range.

Good but needs careful wiring
Works well but make sure to check the jumpers for interface selection. Documentation could be clearer.

Solid build quality
PCB looks clean and soldering is good. Tested up to 3 meters without issues.
Q: Does this work with Raspberry Pi?
A: Yes, it supports 3.3V logic and UART/I2C which are compatible with Raspberry Pi GPIO.
Q: Is a library available for Arduino?
A: Yes, you can use standard NewPing library or our provided example code for UART/I2C modes.
Q: What is the maximum detection angle?
A: The measurement angle is approximately 15 degrees cone.
Q: How do I switch between UART and I2C?
A: There are solder jumpers on the back of the board to select the communication protocol.
Q: Can it measure liquids?
A: No, this ultrasonic sensor is designed for air-based distance measurement only.
