This performance of the ultrasonic sensor distance measuring module is stable, measure the distance accurately. The module is with High precision, blind spots (3cm) super close. This module provides a full set of ranging process.

  • Working voltage : 5V(DC);
  • Static current: Less than 2mA;
  • Output signal: Electric frequency signal, high level 5V, low level 0V;
  • Sensor angle: Not more than 15 degrees;
  • Detection distance: 2cm - 450cm;
  • High precision: Up to 3mm;
  • Mode of connection: VCC / trig(T) / echo(R) / GND.
  • Module Working Principle:
  • Adopt IO trigger through supplying at least 10us sequence of high level signal;
  • The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal.
  • If there is signals returning, through outputting high level and the time of high level continuing is the time of that from theultrasonic. transmitting to receiving
