Add an easy-to-use modern distance sensor to your project.

Much like a bat or submarine, the module uses echolocation to determine the distance from objects from 20 to 4500mm away.

This sensor is pin and software compatible with the maker classic HC-SR04 Ultrasonic sensor used in so many projects with many added benefits.

Using this sensor

Connect the Vcc and Gnd to your development board's IO level power supply, 3.3V for Raspberry Pi, Pico and micro:bit, or 5V for Arduino.

Then Trig and Echo into digital input and output pins respectively.

Once you've got it configured correctly, use your code to take the Input reading from the Echo pin and plug it into the distance formula: distance = (traveltime/2) x speed of sound to get a distance reading.

Examples

Raspberry Pi Pico - Micropython

from machine import Pin, time_pulse_us
import time

# Define the trigger and echo pins
trigger_pin = Pin(5, Pin.OUT)
echo_pin = Pin(4, Pin.IN)

# Define a function to measure the distance
def measure_distance():
    # Trigger the sensor by sending a 10 microsecond pulse
    trigger_pin.on()
    time.sleep_us(10)
    trigger_pin.off()
    
    # Measure the duration of the echo pulse
    duration = time_pulse_us(echo_pin, 1, 30000)
    
    # Convert the duration to distance in centimeters
    distance = duration / 58
    
    return distance

while True:
    distance = measure_distance()
    print(int(distance))
    time.sleep(.3)
