Quick demo for the RCWL I2C ultrasonic
from Adafruit Industries · host Adafruit Industries
The RCWL sensor has a lil solder jumper on the back that lets you turn it into "IIC" mode - we tried it out and ... it kinda works! This sensor can be used on an I2C bus, but it doesn't seem to do well if sharing it with other devices. Still, if you have a microcontroller or microcomputer that doesn't have fast GPIO for toggle/pulse or a hardware UART, you definitely can use it for inexpensive sensing. Note that on this QT Py RP2040 we've got the OLED on a different I2C bus which is why it's happily running for hours now.
