  • Trigger sensing signal 10us TTL, send 0x55
  • Receive measurement signal:
    • MODE-1 (R27 open): pulse width equals to distance.
    • MODE-2 (R27=47K): periodically output range value
    • MODE-3(R27=120K): when receive 0x55, module output 0xFF + data_H + data_L + data_SUM


  • horizontal ranging;
  • obstacle avoidance, automatic control;
  • close to the object, there is a detective
  • traffic control;
  • security, industrial control;
  • artificial intelligence, teaching and research
