Details:
  • Operating voltage : 3-5.5V (DC)
  • Sensor angle: not more than 15 degrees
  • Detection distance:
    • 5V: 2cm-450cm
    • 3.3V: 2cm-400cm
  • High Precision: Up to 0.3cm
  • Input Trigger Signal: 10us TTL impulse
  • Echo Signal : output TTL PWL signal
  • The high-end operational amplifier SGM324, so HC-SR04+ has a wider operating voltage (3V-5.5V)
  • The high-end operational amplifier SGM324, so HC-SR04+ has a smaller operating current (3mA) at the same distance
  • The software and hardware is fully compatible with the current batch of HC-SR04. You can direct replacement
Connection headers:
  • VCC: supply 5V
  • GND: ground wire
  • TRIG: trigger control signal input
  • ECHO: echo signal output
Usage
  • Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not
  • The out pin of this module is used as a switching output when anti-theft module, and without the feet when ranging modules.
  • Note: the module should be inserted in the circuit before been power, which avoid producing high level
    of misoperation; if not, then power again.
Module 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 the ultrasonic transmitting to receiving.
  • Test distance =(high level time * sound velocity (340M/S) / 2.

Note: when installing, connect the GND terminal first, otherwise, the module may get damaged. When testing, the coverage of the tested object is 0.5 square meter or below, and try to make the plate smoothly, otherwise, it will affect the result of the testing.
