8. Read Distance

Through the Ultrasonic Module in its head, PiDog can detect obstacles ahead.

An ultrasonic module can detect objects between 2 and 400 cm away.

With the following function, you can read the distance as a floating point number.

Pidog.ultrasonic.read_distance()

Here is an example of usage:

from pidog import Pidog
import time

my_dog = Pidog()
while True:
    distance = my_dog.ultrasonic.read_distance()
    distance = round(distance,2)
    print(f"Distance: {distance} cm")
    time.sleep(0.5)
