These ultrasonic sensors give robots and automatic vehicles a sense of distance so they can stop or steer around obstacles. They respond in milliseconds and filter noise, so they work in busy, noisy places.

How it works
The sensor sends short ultrasonic pulses and reads the echoes to find the nearest obstacle on the ground. The robot controller reads the distance and decides to slow, stop or steer. Dual-beam types cover a wider area in front of the robot.
