Description

I2C Ultrasonic sensor with compensation

Why did I make it?

I needed a sensor which can be put on an I2C bus and handle distance measuring on its own. This sensor should be able to change I2C address so I can put multiple sensors on a single I2C bus.

What makes it special?

This sensor is small, has variable input voltage 3.3-5V and can I2C address can be set from 0x10 to 0x17.
