I installed newly bought Ultrasonic sensor on my GoPiGo2 car. The sensor is working fine in initial testing with basic_test_all.py. However, I found an issue when running basic_obstacle_avoid.py. A lot of times, us_dist(15) returns value wrong, such as 7 or 6 only.
I searched your forum and ran grove_distance_sensor.py to test. The incorrect values were returned quite frequently.
Is this a product defect or standard behavior?
