  • Size: 41×28.5mm
  • Wire length: 2.5m
  • The device is waterproof, but it couldn’t work underwater. Please note it.
  • High accuracy, strong anti-jamming, small size, easy to use, low voltage, low power consumption.
  • Integrated with wire enclosed waterproof probe, suitable for wet, harsh measurement occasions.
  • This module is easy to use. A control port sends a high level above 10US, so you can wait for the high level output at the receiving port. You can turn on the timer when there is an output. When this port goes low, you can read it. The value of the timer, at this time is the time of the distance measurement, in order to calculate the distance. Such continuous cycle measurement, that is, you can reach the value of your mobile measurement.
  • Low voltage and low power consumption;
  • High measurement accuracy;
  • Strong anti-interference;
  • Integrated enclosed waterproof line probe for wet and harsh measurement applications.

The basic working principle:

  • using IO port TRIG trigger location, to the high level signal of at least 10us;
  • module automatically sends 8 40KHz Fang Bo, automatic detecting whether a signal return;
  • a signal return, a high level is output through the IO port ECHO, the time duration of the high level is ultrasonic from launch to return.
  • The test distance = (high level time * speed of sound (340M/S)) /2
Application:
  • horizontal ranging
  • obstacle avoidance, automatic control
  • objects are close, there is awareness
  • Traffic control
  • Security, industrial control
  • Artificial intelligence, teaching and researc
