Help Grove ultra sonic ranger

Hello Guys

Well I’m making a car that deflects obstacles, using the Ultra sound sensor attached to a servo motor, which turns to the left and to the right, I would like to compare the distance measured on the left with the distance measured at right?

thanks in advance

Dear,
I’m no clear what you said.
When your car come across a obstacle,ultrasonic sensor will detect the distance between them.
The decision turn left or right is made by yourself(your program).
Any question,please leave a message.
