There are two basic congurations for this device:
• I2C (Inter-Integrated Circuit)—a serial computer bus used to
communicate between this device and a microcontroller, such as an
Arduino board (“I2C Interface”, page 4).
• PWM (Pulse Width Modulation)—a bi-directional signal transfer method
that triggers acquisitions and returns distance measurements using the
mode-control pin (“Mode Control Pin”, page 4).
Connector
You can create your own wiring harness if needed for your project or
application. The needed components are readily available from many
suppliers.
