These sensors are fast, fairly easy to use, and low cost. They do require

powering from 5V for best results: connect GND (ground) and VCC to 5V power.

While the Trig signal can be 3V or 5V, the 'return' Echo signal is 5V logic. For

that reason, we include two 10K resistors, use these as a divider to convert the

5V logic level to a safe 2.5V that you can ready with your 3V device.

You can use this sensor with Arduino, CircuitPython (for microcontrollers or

Raspberry Pi) or MakeCode

We carry a large variety of distance sensors here if this fellow isn't what you're

looking for.
