Example Code for Raspberry Pi-Distance Measurement

Hardware Preparation

• Raspberry Pi 4B x 1
• Raspberry IO Expansion Board x 1
• TF03(TOF) Laser Range Sensor(180m) x 1
• Connector x 1

Wiring Diagram

Other Preparation Work

Enable UART on the Raspberry Pi and ensure the sensor is connected to the correct UART pins.

Sample Code

import time

from DFRobot_TFmini import TFMINI

mini = TFMINI()

def main():
    while True:
        if mini.measure():
            distance = mini.getDistance()
            strength = mini.getStrength()
            print("Distance = %.d" % distance)
            print("Strength = %.d" % strength)
            time.sleep(0.5)
        time.sleep(0.5)

if __name__ == "__main__":
    main()

Result

The Raspberry Pi will print the distance and signal strength in the terminal:

Distance = 100
Strength = 688
