The HC-SR04 sonar ranger is not an I2C device. You should not connect it to an I2C bus.
It needs to be connected to two spare gpios. An output gpio for a trigger pulse and an input gpio for the echo signal.
To take a reading you set the trigger gpio high for >10 µs and then set it low. The echo line will read high thereafter until the sonar echo is received when the echo line will be set low. The high time indicates the round trip echo time.
If the round trip time is measured in µs the round trip cms can be calculated from
round trip cms = round trip time / 1000000.0 * 34030
If you power the sonar ranger from 5V (as you should if you want reliable readings) you will need to use a voltage divider to drop the 5V echo output to a Pi gpio safe 3V3.
An old example for a similar ranger is given at http://abyz.me.uk/rpi/pigpio/ex_sonar_ranger.html
